3. This problem refers to Figure 3. There is a solid sphere of radius located at the center of a
hollow (infinitely thin) spherical shell of radius L. Suppose the inner solid sphere has a uniform charge density (this is charge per unit volume), and the outer spherical shell has uniform charge density o (this is charge per unit area). By assumption, & < L. Find the electric field at a point which is at radius r, for (a) r < &, (b) < r < L, and (c) L < r. Make sure you clearly indicate where the electric field points. Try to obtain your answers by applying Gauss Law and the principle of superposition.
