MCQ
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
  • A
    Mass of $A$ and mass of $B$ still remain equal
  • B
    Mass of $A$ increases
  • C
    Mass of $B$ decreases
  • ✓
    Mass of $B$ increases
✓

Answer

Correct option: D.
Mass of $B$ increases
d
(d) Negative charge means excess of electron which increases the mass of sphere $B$.
