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 $q_{3}$ is of opposite sign

Answer 1

Answer: (C)

Remains unchanged

Answer 2

The force will still remain $\frac{q_{1}q_{2}}{4\pi\varepsilon_{0}r^{2}}$
