Hey guys, before I post I want to say that I am still learning this concept and just want clarification. Why do the charges inside a metal or other object that are interacting(repelling for instance) eventually come to rest and not continue to keep moving around constantly repelling one another. To this we assume that the electric field on the inside of the Gaussian object is zero. All of the charge moves to the outside of the objects surface. But I just don't see how the charges just come to rest. And what is the case when there are ALOT of charges inside the metal that are interacting. Due to superposition, they should continue to keep moving? Again, if I sound stupid it's because I am still learning :). Thanks guys!!
