A charge q₁ exerts some force on a second charge q₂. If third charge q₃ is brought near, the force of q₁ exerted on q₂

Given data: There are three charge particle q₁, q₂, and q₃ are given 

Concept Used: Superposition of charge particle 

Detailed Solution: According to superposition principle, 

The force of interaction between two charges does not depends on the presence of any other charge particle. 

It still remains same as $\frac{q_1{q}_2}{4\pi {\epsilon }_0{r}^2}$
