Question

Please help, I am stuck on this one and only have one try left.  Thank you in advance.

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 shows a cross section. Figure gives the net flux o 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 Phi s = 34.0 Times 105 N m2/C What is the charge of the central particle? Give your answers in mu C. What are the net charges of shell A and shell B?

Explanation / Answer

there is some confusion regarding the graph! if my following asnwers do not match, please tell me. I can correct them.

a) q = flux * epsilon_0

= 0.4 * 34* 10^5 * 8.85 * 10^-12

= 12.04 microC

b) qA + q = - 0.8 * 34* 10^5 * 8.85*10^-12

qA = -36.11 microC

c) qB + qA + q = 1.2 * 34* 10^5 * 8.85*10^-12

= 36.11

qB = 36.11 + 36.11 - 12.04

= 60.18 microC
