Question

A charge q1 exerts some force on the second charge q2.If a third charge q3 is brought near,then the force exerted on q2 by q1 increases or decreases?

Answer 1

A charge q1 exerts some force on the second charge q2.If a third charge q3 is brought near,then the force exerted on q2 by q1 decreases.. :)

Answer 2

Explanation:

The force exerted by the charge q1 on q2 will remain same on introduction of a third charge q3 near about of q1 and q2. The force exerted on q2 by q1 will be F1, let us assume, then force on q2 by q3 be F2.

Therefore, the net force of the system will be changed with introduction of charge, but the charge q2 will experience by q1 will still remain same of F1.
