Charge on conductors: An uncharged conductor has a hollow cavity inside of it. Within this cavity there is a charge of +10 µC that does not touch the conductor. There are no other charges in the vicinity. Which statement about this conductor is true? (There may be more than one correct choice.) The inner surface of the conductor carries a charge of -10 µC and its outer surface carries no excess charge. The outer surface of the conductor contains +10 µC of charge and the inner surface contains -10 μC. Both surfaces of the conductor carry no excess charge because the conductor is uncharged. The inner and outer surfaces of the conductor each contain charges of -5 µC. The net electric field within the material of the conductor points away from the +10 μC charge.
