Question details

QUESTION 8 Find the ratio of Q/q for the E-field to be zero at a distance of z 2.64R for the charge distribution and geometry of problem 22.30 of the text30 Figure 22-53 shows two concentric rings, of radii R and R3.00R, 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 u formly distributed charge on the larger ring if the net electric field at Pis zero? R
