A thick spherical shell of charge Q and uniform volume charge density ? is bounded by radii r1 and r2, where r2 > r1. With V = 0 at infinity, find the electric potential V as a function of the distance r from the center of the distribution, considering the following regions. (Use any variable or symbol stated above along with the following as necessary: ?0 and ?.) (a) r > r2 V = ? (b) r2 > r > r1 V = ? (c) r < r1 V = ? (d) Do these solutions agree at r = r2 and r = r1? Yes or No
