Question
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) q0 and q0, (2) -q0 and -q0, and (3) -q0 and q0. Rank the situations according to the magnitude of the net electric field at (a) point P1 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.
Explain your answer with mathematical formulas. You can use Eq. (22-16)
E = qz / 4 pieEchelon0*(z^2 + R^2)^3/2
Explanation / Answer
1)
a) at point P1 , zero (as two equal charges both sides
b) only due to ring A ,due to ring B is zero......
c) due to both and add up
c>b>a
2) same case..........
c>b>a
3) a>b>c
