Two identical metallic spheres of exactly equal masses are taken. One is given a positive charge q coulombs and. other an equal negative charge. Are their masses equal after charging ?

Text Solution

Verified by Experts

The correct Answer is:
No, the mass of the negatively charged sphere (excess of electrons) will be slightly more than that of the positively charged sphere (deficit of electrons).

    The body is positively charged. Then its mass effectively.

    Two identical metallic spheres, having unequal opposite charges are placed at a distance of 0.50 m apart in air. After bringing them in ir contact with each other, they are placed at the same distance apart. Now, the force of repulsion between them is 0.108 N. Calculate the final charge on each of them.

    Predict and explain. An electrically neutral sphere is given a negative charge. (1) In principle, does the object's mass increase, decrease or remain the same after being charged?
