(1) When I ground a conducting metal plate, is all the charge on the plate transferred to earth? By this I mean charge on surface of the plate and charge inside the plate.
Inside metal plate there are free electrons. So all the free electrons are transferred to earth? If yes, then metal plate should become positively charged.
On its surface, then it should have some constant non-zero potential. But when we ground conducting plate, potential on its surface should be zero.
(2) When we put positive charge on a metal plate, what do we put actually? In nature protons are positive charged particles and electrons are negatively charged particles (apart from other elementary particles).
