An insulating spherical shell with the inner radius a = 20.0 cm and the outer radius b = 30.0 cm is uniformly charged with the volume charge density rho = 2.75 mC/m3. Use the Gauss Law to determine the magnitude of the electric field at a point on the surface with the given radius. a) r = 10 cm b) r = 25 cm c) r = 50 cm Hint: you will need the formulas for the surface area of a sphere, the volume of a sphere, and the volume of a spherical shell.

In the figure a solid sphere of radius a = 3.10 cm is concentric with a spherical conducting shell of inner radius b = 2.00a and outer radius c = 2.40a. The sphere has a net uniform charge q1 = +2.51 fC; the shell has a net charge q2 = -q1. What is the magnitude of the electric field at radial distances (a) r = 0 cm, (b) r = a/2.00, (c) r = a, (d) r = 1.50a, (e) r = 2.30a, and (f) r = 3.50a? What is the net charge on the (g) inner and (h) outer surface of the shell? (a) Number Units (b) Number Units (c) Number Units (d) Number Units (e) Number Units (f) Number Units

In Fig. $23-36$, a solid sphere of radius $a=2.00 \mathrm{~cm}$ is concentric with a spherical conducting shell of innet radius $b=2.00 a$ and outer radius $c=2.40 a$. The sphere has a net uniform charge $q_{1}=+2.00 \mathrm{fC}$; the shell has a net charge $q_{2}=-q_{1}$. What is the magnitude of the electric field at radial distances (a) $r=0$, (b) $r=a / 2.00$, (c) $r=a$, (d) $r=1.50 a$, (e) $r=2.30 a$, and (f) $r=3.50 a ?$ What is the net charge on the $(g)$ inner and $(h)$ outer surface of the shell?
