Question:
The electric field at point P just outside the outer surface of a hollow spherical conductor of inner radius 10 cm and outer radius 20 cm has magnitude 450 N/C and is directed outward. When an unknown point charge Q is introduced into the center of the sphere, the electric field at P is still directed outward but is now 180 N/C.
(a) What was the net charge enclosed by the outer surface before Q was introduced?
(b) What is charge Q? After Q is introduced, what is the charge on the
(c) Inner
(d) Outer surface of the conductor?
