capacitor consists of three concentric spherical shells with radii R, 2R, and 3R. The inner  and outer shells are connected by a wire so they are at the same potential. The shells start  neutral, and then a battery transfers charge from the middle shell to the inner and outer  shells. a. If the final charge on the middle shell is -Q, what are the charges on  the inner and outer shells? Your answer should be a function of Q. b. Determine the electrostatic energy of this system in terms of Q.
