A spherical conducting shell of inner radius "a" and outer radius "b" carries a total charge of +5Q distributed on the surface of a conducting shell. The charge at the center is +8Q. (Use the following as necessary: ?0, ?, Q and r.)
(a) Find the electric field exterior to the sphere, for r > b.
E =
(b) What's the electric field inside the conductor, for a < r < b.
E =
(c) Find the charge distribution on the conductor.
