Two identical metallic spheres of exactly equal masses are taken. One is given a poistive charge Q coulombs and the other an equal negative charge. Their masses after charging are different.

Text Solution

Verified by Experts

The statement is ture. The metallic sphere that gets negtively charged gains electons and hence its mass increases. The metallic sphere which gets postively charged loses electons and hence its mass decreases.
