A particle that carries positive charge \(+q\) is located at the center of one or more concentric, thick or thin spherical shells. The shells are either made of a conducting material but are electrically neutral or made of a nonconducting material and have uniform surface charge densities. Figure P24.85 is the graph of the electric flux passing through spherical Gaussian surfaces centered on the particle, as a function of radial distance \(r\) from the particle.

(a) What is the minimum number of spherical shells required to produce the graph?

(b) Describe each shell completely, specifying its charge, its inner and outer radii, and whether it is made of a conducting or nonconducting material.
