If like charges repel and unlike attract why do like particles of matters attract instead of repelling?

like charges attract and unlike repel becoz they have electrostatic forces acting.\nbut gravitationis not a force but a property of matter, so like masses attract rather than repel naturally

Basically, when you rub two certain materials, you will create static electricity, which is named that way because the charges do not _flow_, i.e. there is no current.\n\nNot so basically, but still very primitively, there exist two forms of material: ones that "likes" to "steal" electrons, and ones that "likes" to "give" electrons. Whenever these two are put next to each other, the electrons "jump" from one substance to the other, causing a potential difference, and possibly a spark (if the potential difference is high enough).\n\nRubbing two such materials does not cause this effect. It is a common misconception; when you rub two things you are simply increasing the surface area of contact between the two such substances, thereby creating a more noticeable effect.\n\nand the check spelling button screwed up some of my spelling. fix it yahoo! people, please. especially with the word 'effect' which was changed to 'effectt' and the plural of some words.

It's either just one charge: The electrical, which appears in positive and negative characteristics, or if you see "charge" in a more general way it's more then one charge: magnetism has also a source, but that appears always in dipoles, mass is the "charge" of gravity, but that appears just with a positive sign, and the strong interaction has three kind of charges, called "colour charges": red green and blue.\n\nTwo see an underlaying principle for this "chaos" we need the "Grand Unified Theory" which still is "work in progress" ;)

The formula for attraction between two electromagnetically charged particles is:\n\n(Charge #1) * (Charge #2)\n______________________\n        distance squared\n\nThis means this means that doubling the distance decreases the force by a factor of four.  Your answer is correct.

anti-matter happens to have an opposite charge of matter, like a proton with a negative charge would be anti-matter here.  If matter and anti-matter happened to be in the same space they would cancel eachother out and the only thing left of them would be I think it was either Beta or Gamma rays, mabey Infered.  \n\nDark matter, is something else.  It's a contraversial subject and scientists LOVE to debate about it, I don't know ANYTHING about it, but you could look it up.

The electrostatic force is one of the four fundamental forces. It acts between all charged particles, repulsive between like charges and attractive between unalike charges. Going a bit deeper its origin is in the exchange of carrier particles, which in the case of the electrostatic force are photons.\n\nMagnetism is an effect of special relativity on the electrostatic force. Hence it only applies between moving charges. An electron will have no response to a magnetic field if it is not moving and the field is not changing. Otherwise it will move perpendicular to both its path and the magnetic field.

This is a very good question. Ultimately it comes down to being one of the fundamental features of our universe. But it can also be broken down a bit.\n\nLike charges repel, and opposite ones attract because of differences in their electric fields. But the electric fields are really part of the larger electromagnetic force. This force is mediated by photons (light) and, indeed light is a self-propagating electromagnetic wave.\n\nBut there are also three other fundamental forces: gravity, the strong nuclear force and the weak nuclear force. The strong nuclear force is well, strong, but very short range. It holds the protons and neutrons together in a nucleus (otherwise the like charges from the protons would break up every nucleus except hydrogen). The weak nuclear force is sort of a miscellaneous, and comes into play in certain radioactive decay sequences.\n\nIn the 1980s it was shown that the electromagnetic and weak forces are actually the same thing. The difference we observe is that the universe is, relatively speaking, "cold," and these two parts have separated out. It is sort of like having a glass of steam (one thing) which cools down until there is water and ice (two things). The water and ice look a lot different from each other, but are fundamentally the same. In the same way in the very, very early universe when things were a lot hotter, the electromagnetic and weak forces were identical - like the steam in the analogy.\n\nMore recently it was found that the strong force can also be linked to the "electroweak" force in the same sort of manner. The mathematical and physical details are different from "electroweak unification" but the basic principle is the same. It was from this Grand Unification of the electromagnetic, weak, and strong forces the the theoretical notion of quarks came. This GUT has been tested and the experiments show it is right on target.\n\nThe next step is to connect the electro-weak-strong force with gravity. This is a lot harder because the first three are understood in the context of Quantum Mechanics and gravity is understood with General Relativity. QM and GR are not compatible on some basic principles.\n\nOne approach that is being tried to combine QM and GR is with string theory. To make this work the universe is composed of 11 dimensions, the usual 3-spatial and 1-temporal dimentsion, plus 7 very, very small spatial dimensions. If these extra 7 are looped around themselves so that they are vastly "smaller" than a proton, we'd never really notice them.\n\nWhat string theory seems to suggest is that there are just some ways to make stuff in the universe, and one of these ways is to create the "force particles" that mediate the fundamental forces.\n\nSo, extrapolating that, and realizing that string theory is in no sense proven, we can say that "like charges repel" because of the geometry (the 11-dimensions) of the universe.\n\nBut string theory remains far from being complete mathematically, and no one can really make solid predictions yet to test it. So, you can also fall back on the answer in the first paragraph.

Like charges repel, right?\nA nucleus is full of like charges and it takes a lot of force to hold them together.  This is "the strong force".  If a nucleus is big enough, like uranium, that balance is pushed to the ragged edge so chunks break off.  Hence, radiation.\nThats the simple version, but you get the pic.

Magnetic forces - magnetism - like force repel ( + to + or - to -)(repulsion) and opposite force attract (+ to -, - to +) (attraction).

There are two types of charges positive and negative.\n\nAll objects have equal number of charges in general.\n\nWhen the net charges are equal to zero, the body  is in neutral.\n\nBy various methods like friction, we can remove one or other type of charges from an object.\n\nThen an object is either positively charged or negatively charged.\n\nIn this state, the charges, residing in the object are rest; Static.\n\nThe study of these behaviors of charges at rest is Static Electricity.

The electric field will be repellent between protons, attractive between a proton and an electron.\n\nThere is, of course, the nuclear force--which is exerted only at extremely close range, and is an attractive force.\n\nThere is also the gravitational force between them, also attractive, but it's pretty trivial with such microscopic masses, unless you get unthinkably close.\n\nGravity, of course, would be there between the proton and the electron, but it's a whale of a lot more feeble between that pair than between a pair of protons...

Particle physicists make this kind of reaction happen every day in laboratories. This accomplished by accelerating ordinary particles up to very high speeds, close to the speed of light, and smashing them into each other. In an interesting collision, the result is a spray of new particles, many of which may be heavier than the original pair that collided. The energy of motion of the orignal particles has contributed to creating new ones. Some of these new particles are very interesting and exotic! Most only live for a short time before decaying into more ordinary stuff. \n\nIt is in this way that scientists have found out what kinds of particles exist. The world is made up of stable particles, and we only know about the unstable ones because we have been able to create them in the laboratory out of the energy in the collisions. \n\nThere are rules of course. Whenever a particle is made, certain things have to add up. The energy has to add up, of course. The total electrical charge cannot change, and so when many kinds of particles are made, the same number of antiparticles must also be made (some particles are their own antiparticles so you can make one of these at a time. Photons are examples of this). Antimatter annihilates with corresponding matter particles, and the result is eventually photons, leaving no net new matter.

Negatively charged ion has one/some extra electrons than the corresponding neutral atom. so, deu to repulsion they stay more apart.\n\nthat is what i think is the reason why -ve ions have greater radious than neutral atom.

Charged particles will turn in a magnetic field.  That, coupled with the ability to make a charged particle flee a like charge makes it possible to force a particle to zip around at high speed.

Corresponding to each kind of particle, there is an associated antiparticle with the same mass and spin. Some particles, such as the photon, are identical to their antiparticle; such particles must have no electric charge, but not all charge-neutral particles are of this kind. The laws of nature were thought to be symmetric between particles and antiparticles until CP violation experiments found that time-reversal symmetry is violated in nature. The observed excess of baryons over anti-baryons in the universe is one of the primary unsolved problems in cosmology.

Charge is a fundamental property. This means that we simply accept charge as an attribute of the particles. Much like we accept a person's name.\n\nIn other words, we don't know what causes charge in the sense which you inquire to know, but it doesn't prevent us from working with the particles.\n\nCharge aside, electrons and protons are very different particles. Electrons orbit atoms and weight next to nothing, while protons are locked in the nucleus of the atom and are considerably more massive.
