Q.
Statement I: Two charges $q_{1}$ and $q_{2}$ are placed at separation $r$. Then magnitude of force on each charge is $F$. Now a third charge $q_{3}$ is placed near $q_{1}$ and $q_{2}$. Then force on $q_{1}$ due to $q_{2}$ remains $F$.
Statement II: Force of interaction between two charges is independent of presence of other charge.
