Electric field, E, is\n\nE = K*q/(r^2)\n\nAt the "neutral point" the electric fields from each point will be equal in magnitude, but opposite in direction, and sum to zero (a charged particle placed at this point would be equally attracted to each point charge).  That is:\n\nE1 + E2 = 0\nE1 = -E2\n\nThe form E is give in above is a scalor, not a vector, so has no direction- therefore, we'll say that the magnitude of |E1| = |E2|\n\nK*Q/(r1^2) = K*4Q/(r2^2)   \n1/(r1^2) = 4/(r2^2)       (eq 1)\n\nI'll assume that this is linear distance, since I don't have any other information. This means that \n\nr1+ r2 = 12 cm             (eq 2)\n\nSolving equation 1 for r2 gives:\n((r1^2)*4)^0.5 = (r2^2)^0.5  \n\nr2 = r1*2\n\nsubstituting into equation 2:\n r1 +r1*2 = 12cm\n\nr1 = 4cm\n\nSo the distance from Q to the neutral point is 4 cm

Sorry, but with the time you spent typing these questions you could of looked them up in your physics book or googled them.  Sometimes getting others to do your leg work isn't always the best answer to a problem.  Good Luck in your new class!

You're in luck.  I teach physics and I know exactly how to answer this question (it's based on the work-energy principle).  It's pretty simple, really.  But it would be best if we discussed it by messenger.  Yahoo Messenger me, my ID is\nfortitudinousskeptic\n\n- Kevin

Check the Michaelis-Menten equation.It's too long to write it all down for you ;)

I've alread answered two of your questiions in my last answer....\n\nIn this one, the guys above are correct - however, I'd try working it out for myself if I was you. Your tutor will soon realise something is wrong if you are giving answers to a subject you don't understand. Read the chapter, ask you teacher if you need more help. Learn Newtonian mechanics for yourself.
