Problem
A hollow conducting shell initially carries a net charge of +8μC distributed on its outer surface. A point charge of −3μC is then inserted through a small insulating hole and fixed at the center of the cavity without contacting the shell. After electrostatic equilibrium is re-established, determine (i) the charge induced on the inner cavity surface and (ii) the charge that remains on the outer surface of the shell.
