  • question_answer
    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 [AMU 1995; RPET 2000; CPMT 2000]           

    A)                    Mass of \[A\] and mass of \[B\] still remain equal           

    B)                    Mass of \[A\] increases           

    C)                    Mass of \[B\] decreases           

    D)                    Mass of \[B\] increases

    Correct Answer: D

    Solution :

                 Negative charge means excess of electron which increases the mass of sphere B.
