First post,
I know that charges of the same sign repel one another and that will attempt to move as far away from one another as possible. Now, I'm reading my physics textbook and it says charges will always move to the outer surface of a conductor even if the inner surface has a larger area. Think of a hollow sphere that has a pitted inner surface to give it more surface area than the outer.
Now why is this? My best guess is that because the electric field in a conductor is zero? What obvious thing am I missing here?
Thanks!
