A point charge

q = −4.0 ✕ 10−12 C

is placed at the center of a spherical conducting shell of inner radius 3.4 cm and outer radius 3.9 cm. The electric field just above the surface of the conductor is directed radially outward and has magnitude 7.5 N/C.

a) What is the charge density (in C/m2) on the inner surface of the shell?

b) What is the charge density (in C/m2) on the outer surface of the shell?

c) What is the net charge (in C) on the conductor?
