Two bodies A and B are charged with equal magnitude of charge but A with positive charge and B with negative. If $$M_A$$ and $$M_B$$ are masses before charging and $$M'_A$$ and $$M'_B$$ are the masses after charging, then $$m_0$$ is some constant mass.

A

$$M'_A=M_A+m_0$$ and $$M'_B=M_B-m_0$$

B

$$M'_A=M_A-m_0$$ and $$M'_B=M_B+m_0$$

C

$$M'_A=M'_B$$

D

$$M'_A=M_A-\frac{m_0}{2}$$ and $$M'_B=M_B+m_0$$
