Question

An uncharged conductor has a hollow cavity inside of it. Within this cavity, there is a charge of +10μC 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 outer surface of the conductor contains+10μC of charges and the inner surface contains-10μC.

b. The net electric field within the material of the conductor points away from the +10μC charge.

c. The inner surface of the conductor carries a charge of -10μC and its outer surface carries no excess charge.

d. Both surfaces of the conductor carry no excess charge because the conductor is uncharged.

e. The inner and outer surfaces of the conductor each contain charges of -5μC.
