Question
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 23-33a shows a cross section. Figure 23-33b gives the net flux ? through a Gaussian sphere centered on the particle, as a function of the radius r of the sphere. The scale of the vertical axis is set by ?s = 37.0 ? 105 N?m2/C. (a) What is the charge of the central particle? Give your answers in ?C. What are the net charges of (b) shell A and (c) shell B?
Explanation / Answer
charge of the central particle= 8.85*10^-12*37*10^5*2/5 =1.31*10^-5 C net charge of shell A=8.85*10^-12*37*10^5*(-6)/5 =-3.92*10^-5 C net charge of shell B=8.85*10^-12*37*10^5*10/5 =6.55*10^-5 C
