Consider a neutral conducting sphere. A positive point charge is placed outside the sphere. The net charge on the sphere is then

Options

A. Negative and uniformly distributed over the surface of sphere
B. Positive and uniformly distributed over the surface of sphere
C. Negative and appears at a point the surface of sphere closest to point charge
D. Zero

Answer

D

Explanation

Due to electrical induction negative charge appears near the external charge and positive charge appears on the opposite end. But the total charge of the sphere doesn.t change and remains zero.
