The figure shows two concentric rings, of radii R and R-2.61R, that lie on the same plane. Point P lies on the central z axis, at distance D-2.60R from the center of the rings. The smaller ring has uniformly distributed charge Q-5.00 10°C. What is the uniformly distributed charge on the larger ring if the net electric field at Pis zero?
