Chapter 21, Problem 74P
A solid sphere of radius R carries a uniform volume charge density ρ. A hole of radius R/2 occupies a region from the center to the edge of the sphere, as shown in Fig. 21.38. Show that the electric field everywhere in the hole points horizontally and has magnitude ρR/6ε0. Hint: Treat the hole as a superposition of two charged spheres with opposite charges.
