Transcribed Image Text:30 GO Figure 22-53 shows two
concentric rings, of radii R and
R' = 3.00R, that lie on the same
plane. Point P lies on the central z
axis, at distance D = 2.00R from the
center of the rings. The smaller ring
has uniformly distributed charge
+Q. In terms of Q, what is the uni-
formly distributed charge on the
larger ring if the net electric field at
Pis zero?
