A metallic sphere is charged negatively, Will its mass increase, decrease or remain the same?

Text Solution

Verified by Experts

When the sphere is negatively charged, it means electrons have been added to it. Since electrons have infinite mass, the mass of the negatively charged sphere will increase.
