Consider a neutral conducting sphere .a positive point charge is placed out side the sphere the net charge on the sphere is

A) negative and disturbed uniformly over the surface of the sphere

B) negative and appears only at the point on the sphere closest to the point charge

C) negative and distributed non uniformly over the entire surface of the sphere

D) zero

Open in App

Solution

Answer is option (D) zero

Explanation:
A negative charge will be induce on the outer surface of the sphere which means that the positive point charge will attract the negative charge and it will accumulate on the outer surface of the sphere, but the thing to be remembered is that still the total charge inside the sphere is same and constant ,i.e, it is still electrically neutral which means that the net charge on the sphere is still zero.
