Set 7 Problem 4 Potential of a Charged Spherical Shell A hollow spherical conductor, carrying a net charge +@ = 49 pC, has inner radius 1 = 5.1 cm and outer radius r2 = 13 cm. At the center of the sphere is a point charge +Q/2. a. Find the potential at r = 18.0 cm. O. V = 3.225 V abc sin(x) Ox10 3.225 Submit Reset Reset All First, use Gauss' law to find the electric field in each region. Then, integrate to find the potential, using the fact that the electric potential is zero an infinite distance from the sphere. b. Find the potential at r = 10.0 cm.
