In figure, two positive charges q2 and q...

In figure, two positive charges `q_2` and `q_3` fixed along the y-axis, exert a net electric force in the + x direction on a charge `q_(1)` fixed along the x-axis. If a positive charge Q is added at (x, 0), the force on `q_(1)`

A

shall increase along the positive x-axis.

B

shall decrease along the positive x-axis

C

shall point along the negative x-axis.

D

shall increase but the direction changes because of the intersection of Q with `q_2` and

Text Solution

Verified by Experts

The correct Answer is:
A
The resultant force acting on `q_1` by `q_2` and `q_3` is in + x-axis.

It means, `q_2` and `q_3` apply attractive force on `q_(1)` Hence, it can be said that qx is negative and `q_2` and `q_3` are positive. Now, if + Q charge is placed at (x, 0) then attraction force on negative charge ql will be in + x-axis. Hence, net force will be in + x-axis.
