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 x 10-6 C. What is the uniformly distributed charge on the larger ring if the net electric field at P is zero? D R' Number i Units
