2. A point charge q is placed at the center of a spherical conducting shell of inner radius a and
outer radius b. The electric field just above the surface of the conductor is directed radially
outward and has magnitude E. Write expressions for the following:
(a) The charge density on the inner surface of the shell.
(b) The charge density on the outer surface of the shell.
(c) The net charge on the conductor.
(d) Evaluate your expressions for q = -3.5 x 10-12C, a = 5.5 cm, b = 7.0 cm, E = 8.0 N/C.
Recall: the charge per unit area at each surface is the charge density at that surface.
