2. The figure below shows a circular ring placed in the yz plane. The radius of the ring is R =15 cm and it has a total charge of Q = 38C. P Y 0. The coordinate of p is (20, 0,0) in cm. [2] b. If we place another ring of radius R' = 20 cm with the same charge on the yz plane concentric with the first ring, then calculate the potential at point P. c. Calculate the net electric field at P due to both the rings. [4] [4] 2. The figure below shows a circular ring placed in the yz plane.
