Question

A neutral conductor contains a hollow cavity in which there is a +100 nC point charge. A charged rod then transfers - 50 nC to the conductor. Afterward, what is the charge (a) on the inner wall of the cavity, and (b) on the exterior surface of the conductor

Answer 1

Answer:

Explanation:

charge inside the cavity is + 100 nC

charge transfer by the rod is - 50 nC

(a) charge on the inner wall of the cavity is - 100 nC.

(b) Charge on the exterior surface of the conductor = - (-100) + (-50)

                                                                                      = 100 - 50 = 50 nC.
