(a) Can two bodies having like charge attract each other (yes/No)
(b) Can a charged body attract an unchanged body? (yes/No)
(c ) Two identical metallic spheres of exactly equal masses are taken, one is given a positive charge q and the other an equal negative charge. Their masses after charging are different. Co,,ent on the statement.

Text Solution

Verified by Experts

(a) yes. Two bodies are placed close to each other where one has much more charge than the other. Then due to induction, force of attraction becomes more than force of repulsion.
(b) Yes, due to induction effect.
(c ) yes, mass of negatively charged sphere will be more.
