what is the relationship between electrostatic force and distance?

In electrostatics, the electrical force between two charged objects is inversely related to the distance of separation between the two objects. Increasing the separation distance between objects decreases the force of attraction or repulsion between the objects.

Voltage, also called electromotive force, is a quantitative expression of the potential difference in charge between two points in an electrical field. Electric power is the rate, per unit time, at which electrical energy is transferred by an electric circuit. ... This potential difference or emf causes electrons to move .

Electric Potential Energy and Potential Difference Electric potential energy results from forces between charges; potential difference is the energy needed to move a charge from point A to B.

The electric field is an alteration of space caused by the presence of an electric charge. The electric field mediates the electric force between a source charge and a test charge. The field is a vector; by definition, it points away from positive charges and toward negative charges.

Relation between Electric Intensity and Potential Gradient The change of electric potential with respect to distance is called potential gradient. It is denoted by dv/dx. hence, the negative of potential gradient is equal with electric field intensity.

The electric potential tells you how much potential energy a single point charge at a given location will have. The electric potential at a point is equal to the electric potential energy (measured in joules) of any charged particle at that location divided by the charge (measured in coulombs) of the particle.

Dipole-dipole forces are attractive forces between the positive end of one polar molecule and the negative end of another polar molecule. ... They are much weaker than ionic or covalent bonds and have a significant effect only when the molecules involved are close together (touching or almost touching).

The relationship between potential and field (E) is a differential: electric field is the gradient of potential (V) in the x direction. This can be represented as: Ex=−dVdx E x = − dV dx . Thus, as the test charge is moved in the x direction, the rate of the its change in potential is the value of the electric field.

The electromotive force is the measure of energy that it gives to each coulomb of charge, whereas the potential difference is the amount of energy used by the one coulomb of charge. The electromotive force is represented by the symbol ε whereas the symbol V represents the potential difference.

The potential difference is the work done per unit charge. The dimensional formula for potential difference is dimension of work/dimension of charge =dimensions of mass times acceleration times distance/ dimension for charge =M^1L^1T^-2L^1 / A^1T^1 = M^1 L^2 T^-3A^-1 HENCE OPTION "C" IS CORRECT.

At point P in an electric field, the magnitude of the electrostatic force on a proton is 4.0∗10−10N.

Electric field is described as the amount of force per charge while the Electric potential is described as the amount of energy or work per charge. 3. Electric field is a vector quantity while Electric potential is a scalar quantity.

['We can find distance using inverse square law I.e.', 'F = 4π x epsilon x q1xq2/r²', 'Where F is force, epsilon is permittivity constant.. q1,q2 are magnitude of charges and r is distance between them.']

Another difference between the two forces is the fact that gravitation only attracts, while electrical forces attract when the electrical charges are opposite and repel if the charges are similar. Thus, gravitation is considered a monopole force, while electrostatics is a dipole force.

Electric field is defined as the electric force per unit charge. The direction of the field is taken to be the direction of the force it would exert on a positive test charge. The electric field is radially outward from a positive charge and radially in toward a negative point charge.

Work, Force and Distance. In physics, force is the energy required to move an object, and distance is how far the object travels. Work only occurs when a displacement of distance has occurred. For example, in physics, if you push on a car, but no movement has happened, work has not occurred.

Electrostatic force is the force between static (not moving relative to each other) electric charges. Electromagnetic forces are any interactions due to photon exchange and INCLUDES electrostatic forces.
