Question

One metallic sphere A is given a positive charge whereas another identical metallic sphere B of exactly the same mass as A is given an equal amount of negative charge. Then

Options

• mass of A and mass of B still remain equal.

• mass of A increases.

• mass of B decreases.

• mass of B increases.

Answer 1

mass of B increases.

Explanation:

A negative charge refers to an excess of electrons in sphere B, which increases its mass. In sphere A, a positive charge is created by removing electrons.
