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

Question

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 (A) decreases (B) increases (C) remains unchanged (D) increases if q3 is of same sign as q1 and decreases if q3 is of opposite sign.

The force of q1 or q2 is not affected by q3. However, resultant force on q2 will be affected.

Q. 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 $q_{2}$

decreases

increases

remains unchanged

increases if $q_{3}$ is of same sign as $q_{1}$ and decreases if $q_{3}$ is of opposite sign.

The force of $q_{1}$ or $q_{2}$ is not affected by $q_{3}$ . However, resultant force on $q_{2}$ will be affected.
