An irregular neutral conductor has a hollow cavity inside of it and is insulated from its surroundings. An excess charge of 20.0 nC is sprayed onto this conductor.

A) Find the charge on the inner surface of the conductor. Q = ?

B) Find the charge on the outer surface of the conductor. Q = ?

C) Without touching the conductor, a charge of -12.0 nC is inserted into the cavity through a small hole in the conductor. Find the charge on the inner surface of the conductor in this case. Q = ?

    Since like charges repel, the charge all goes to the outside of the conductor.

    redbeard is right, it'll just take some thinking to get it.

    A) Q=0 nC

    B) Q=20 nC

    C) Q=12 nC

    [D) Find the charge on the outer surface of the conductor in this case]

    Use the difference between B and C..
