Question

A charge $q_1$ exerts some force on a second charge $q_2$. If third charge $q_3$ is brought near, the force of $q_1$ exerted on $q_2$

• A. Decreases
• B. Increases
• C. Remains unchanged
• D. Increases if $q_3$ is of the same sign as $q_1$ and decreases if $q_2$ is of opposite sign

Answer 1

The correct option is C Remains unchanged

The force will still remain $\frac{q_1{q}_2}{4\pi {\epsilon }_0{r}^2}$
