Question

One metallic sphere A is given positive charge whereas another identical metallic sphere B of exactly same mass as of A is given 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

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

Explanation:

Sphere A is given as a positive charge, so it will lose some electrons, hence its mass will decrease.

Sphere B is given as a negative charge, so it will gain some electrons, hence its mass will increase.
