Question
he Figure shows two parallel non conducting rings with their central axes along a common line. Ring 1 has uniform charge q1 and radius R; ring 2 has uniform charge q 2 and the same radius R. The rings are separated by a distance d = 3.00 R. The net electric field at point P on the common line, at distance R from ring 1, is zero. What is the ratio
q1/q2 ?

sol The field along the axis of a ring at distance "x" from the center is; as we know E = kq/(x^2 + R^2) , (R = radius of ring) That should help clear up things.
