Question
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 net flux through a Gaussian sphere centered on the particle,as a function of the radius r of the sphere. The scale ofthe vertical axis is set by s = 30.0× 105 N·m2/C.(a) What is the charge of the central particle?Give your answers in µC. What are the net charges of(b) shell A and (c)shell B?
Explanation / Answer
(b) The next value that takes is – 4.0 × 105 (in SI units), which implies
