A solid insulating sphere of radius R has a charge of Q, (Q > 0) placed on it, uniformly distributed throughout its volume. Surrounding the sphere is a spherical conducting shell with inner radius 2R and outer radius 3R and has a charge of −2Q placed on it. The sphere and the shell share the same center.
1A: Determine the magnitude of the electric field, E(r), where r is the distance from the center of the sphere
1B: Determine the electric potential, V (r), setting V (∞) = 0
3C: Graph V (r)
