When a positive point charge is placed outside a conducting sphere, a rearrangement of charge takes place on the surface as shown in the figure. But net charge on the sphere is zero as no charge has left or entered the sphere.

Solution

Q.
Consider a neutral conducting sphere. A positive point charge is placed outside the sphere. The net charge on the sphere is then [2007]

1 negative and distributed uniformly over the surface of the sphere

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

3 negative and distributed non-uniformly over the entire surface of the sphere

4 zero
