Problem 1: An insulating sphere of radius 4 has a uniformly distributed charge. Evenly throughout the entire mass, Q is placed within the shape. A round conductor with a charge of -20, which has an internal radius of 6 and an external radius of C, is placed so that the centers overlap exactly as shown in the figure. (a) Describe the distribution of charge on a hollow sphere. When this system is in electrostatic equilibrium (b) Calculate the electric field, E, in regions 1, 2, 3, and 4 using Gauss's Law. (c) Draw a graph showing the relationship between the electric field, E, and the distance 1. E -20
