An irregular neutral conductor has a hollow cavity inside of it and is insulated from its surroundings. an excess charge of 16.0 nc is sprayed onto this conductor. part a: find the charge on the inner surface of the conductor.
part b: find the charge on the outer surface of the conductor.
part c: without touching the conductor, a charge of -10.0 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.
part d: find the charge on the outer surface of the conductor in this case.
