In Fig. 22-25, two identical circular nonconducting rings
Chapter , Problem 6(choose chapter or problem)
In Fig. 22-25, two identical circular nonconducting rings are centered on the same line. For three situations, the uniform charges on rings A and B are, respectively, (1) qo and qo, (2) -qo and -qo, and (3) -qo and qo. Rank the situations according to the magnitude of the net electric field at (a) point PI midway between the rings, (b) point P2 at the center of ring B, and (c) point P3 to the right of ring B, greatest first.
