Chapter , Problem 23(choose chapter or problem)
Figure 22-47 shows two parallel nonconducting rings with their central axes along a common line. Ring 1 has uniform charge q1 and radius R; ring 2 has uniform charge q2 and the same radius R. The rings are separated by distance d ! 3.00R.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?
