Problem 1 An isolated conducting sphere of radius r; = 0.20 m is at a potential of ~2000v, with charge an. The charged sphere is then surrounded by an uncharged conducting sphere of inner radius r; = 0.40 m, and outer radius r; = 0.50m, creating a spherical capacitor. (a) {5 points) Draw a clear physics diagram of the problem. (b) {5 points) Determine the charge Q0 on the sphere while its isolated. (c) {8 points) A wire is connected from the outer sphere to ground, and then removed. Determine the magnitude of the electric field in the following regions: R
