Flux and nonconducting shells. A charged particle issuspended at the center of two concentric spherical shells that arevery thin and made of nonconducting material. Figure (a) belowshows a cross section. Figure (b) below gives the netflux Φ through a Gaussian sphere centered onthe particle, as a function of the radius r of the sphere. The scale of the vertical axis is setby Φs = 6.0 ×105 N·m2/C. (a) What is the charge of the central particle? Give your answers inµC. What are the net chargesof (b) shell A and (c) shell B?
