A solid, insulating sphere of radius a has a uniform charge density p and total charge Q. Concentric with this sphere is an uncharged, conducting hollow sphere whose inner and outer radii are b and c, as shown in figure. (A) Find the magnitude of the electric field in the regions r < a, a < r < b, b < r < c, and r > c (B) Determine the induced charge per unit area on the inner and outer surfaces of the hollow sphere.
