A solid plate made out of copper has total positive charge Q placed on it. When the plate is in static equilibrium, which of these statements is correct? I. The excess charge +Q will reside on the surface of the conductor only. II. Some of the excess charge +Q will be distributed in the interior of the conductor, and some over the surface. III. E is zero in the interior of the conductor. IV. At the surface of the conductor, E due to the excess charge is perpendicular to the surface. V. At the surface of the conductor, E due to the excess charge may have components which are both parallel and perpendicular to the surface. I, III only 1, III, V only O Il, IV only 11,III,V only 1, III, IV only
