This is a HW problem for my AP Physics class ....i've been pondering over reasons.....but would like some more "educated" input IF a charged glass rod is held near one end of an insulated uncharged metal rod, electrons are drawn to one end. (basically i'm thinking induction here ) a. Why does the flow of electrons cease? After all, there is an almost inexhaustible supply of them in the metal rod. b. Does any net electrial force act on the metal rod?
