Question

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

Answer 1

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.

Answer 2

Answer: The net charge on the sphere is zero.

Explanation:

Induction: The charged body is brought near to the uncharged body without touching together. The charge is induced on the uncharged body in this process.

In the given problem, a positive point charge is placed outside the neutral conducting sphere. Then the negative charge will induce on the outer surface of sphere. The negative charge will accumulate on the surface of the sphere. But the net charge on the sphere is zero. It is electrically neutral.
