A metal ball of radius R placed inside an electrically neutral insulated thick-walled metal sphere is given a charge q0. The centers of the ball and the sphere coincide. The internal radius of the sphere is equal to sqrt(2)R, the external radius is 2R. The ball and the sphere were connected by a wire of insignificant capacity and then separated. How did the potential energy of the system change?
