PHY 102 Electrostatics: Electric Charge and Coulomb's Law Objective Question
Take CBT

Question

What happens to the outer surface of a neutral conductor if a +q charge is placed in its internal cavity?
Options
A It becomes negatively charged with -q.
B It remains neutral.
C It becomes positively charged with +q.
Correct Answer
D The charge on the outer surface becomes zero.
Correct Answer

Option C is the correct answer.

Detailed Explanation

Since the conductor was originally neutral, inducing -q on the inner surface leaves a net +q to be distributed on the outer surface.

Hint

Conservation of charge on the whole conductor.
