Question
Flux and conducting shells. A charged particle is held at the center of two concentric conducting spherical shells. The figure on the left shows a cross section. The figure on the right 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 = 3.5
Flux and conducting shells. A charged particle is held at the center of two concentric conducting spherical shells. The figure on the left shows a cross section. The figure on the right 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 = 3.5 times 106 N*m2/C. What is the charge of the central particle? What is the net charge on shell A? What is the net charge on shell B?

flux = qenc/e0
qenc = e0 flux
a) qenc = -1.8*8.85E-12*3.5E6=-5.58E-5 C
b) qenc = 0.8*8.85E-12*3.5E6 = 2.478E-5 C
Q -5.58E-5 = 2.478E-5
Q = 2.478E-5+5.58E-5=8.058E-5 C
c) qenc = -0.4*8.85E-12*3.5E6=1.239E-5 C
Q +8.058E-5 - 5.58E-5 = 1.239E-5
Q = 1.239E-5 + 5.58E-5 - 8.058E-5=-1.239E-5 C
