10 C of charge are placed on a spherical conducting shell.A particle with a charge of -3 C is placed at the center of the cavity.The net charge on the inner surface of the shell is:
A)-7 C
B)-3 C
C)0 C
D)+3 C
E)+7 C

Question

Quizplus · Accepted Answer

The charge on the inner surface of the shell will be equal and opposite to the charge placed at the center to maintain electrostatic equilibrium, so it will be +3 C.
