$A$ point charge $q_1$ exerts an electric force on a second point charge $q_2$. If a third charge $q_3$ is brought near,the electric force of $q_1$ exerted on $q_2$:
- ADecreases
- BIncreases
- CRemains unchanged
- DIncreases if $q_3$ is of same sign as $q_1$ and decreases if $q_3$ is of opposite sign
