Flux and nonconducting shells. A charged particle is suspended at the center of two concentric spherical shells that are very thin and made of nonconducting material. Figure 23-31a shows a cross section. Figure -1-31b gives the net flux through a Gaussian sphere centered on the particle, as a function of the radius r of the sphere. (The vertical axis is marked in increments of 1.0 106 N·m2/C.) Figure 23-31
(a) What is the charge of the central particle? µC
(b) What is the net charge of shell A? µC (c) What is the net charge of shell B? µC
