O Flux and nonconducting shells. A charged particle is sus pended at the center of two concentric spherical shells that ar very thin and made of nonconducting material. Figure 23-37 shows a cross section. Figure 23-37b gives the net flux through Gaussian sphere centered on the particle, as a function of the ra dius r of the sphere. The scale of the vertical axis is set by d,- 5.0 x 10° N- m/C. (a) What is the charge of the central particle What are the net charges of (b) shell A and (c) shell B? 14 (a) (b) D(10° N m/C)

A long hollow thin-shelled insulating cylinder has a radius R and a uniform surface charge densityσ. At the center is an infinite line of charge with linear charge density λ. What is the electric field a distance rfrom the central axis? Give ansers for r < R and r> R

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 (a) shows a cross section. Figure (b) 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 = 6.0 x 105 N-m²/C. (a) What is the charge of the central particle? What are the net charges of (b) shell A and (c) shell B? (a) B (105 N·m²/C) e -Os r
