[" QNo: "20" 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 "]

Two identical metallic spheres A and B of exactly equal masses are given equal positive and negative charges respectively. Then

A hollow metallic sphere is charged. Insider the sphere

An isolated conducting sphere is given a positive charge by rubbing. Its mass

An isolated solid metallic sphere is given +Q charge. The charge will be distributed on the sphere

(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.
