Question

A charged particle is held at the center of two concentric conducting spherical shells. Figure (a) shows a cross section. Figure (b) gives the net flux $\Phi$ 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 $\Phi_s = 5.0 \times 10^5 \text{ N} \cdot \text{m}^2/\text{C}$. What are (a) the charge of the central particle and the net charges of (b) shell A and (c) shell B? (a) Number 00000177 Units C (b) Number -00000531 Units C (c) Number 00000885 Units C If you mentally construct a Gaussian sphere concentric with the smaller shell but with a smaller radius, what do the plotted flux and Gauss' law reveal about the charge enclosed by the sphere, hence that of the particle? How about a Gaussian sphere with a radius between the radii of the two shells?
