question 9

Multiple Choice

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.)

• A) The inner surface of the conductor carries a charge of -10 µC and its outer surface carries no excess charge.
• B) The inner and outer surfaces of the conductor each contain charges of -5 µC.
• C) The net electric field within the material of the conductor points away from the +10 µC charge.
• D) The outer surface of the conductor contains +10 µC of charge and the inner surface contains -10 µC.
• E) Both surfaces of the conductor carry no excess charge because the conductor is uncharged.
