A conducting spherical shell (see the figure) has inner radius = 10.0 cm, outer radius = 15.0 cm, and has a+3.0μC point charge at the center. A charge of -3.0μC is put on the conductor.(Figure)

Part A

Where on the conductor does the -3.0μC end up?

Where on the conductor does the end up?

a ) on the inner surface of the shell

b ) on the outer surface of the shell

Part B

What is the electric field just inside the shell?

Part C

What is the electric field just outside the shell?
