Question

A solid, insulating sphere of radius a has a uniformcharge density of and a total charge of Q.Concentric with this sphere is an uncharged, conducting hollowsphere whose inner and outer radii are b and c,as shown in the figure above. (Use rho for ,epsilon_0 for 0, and Q,r, a, b and c, asneeded.)
(a) Find the magnitude of the electric field inthe following regions.
r < a
