In figure two positive charges q(2) and ...

In figure two positive charges `q_(2)` and `q_(1)` 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` and `q_(2)` and `q_(3)`

Text Solution

Verified by Experts

The correct Answer is:
A
Since positive charges `q_(2)` and `q_(3)` exert a net force in the `+x` direction on the charge `q_(1)` fixed along the `x-axis` the charge `q_(1)` is negative.Obviously due to addition of positve charge `Q` at `(x,0)` the force on `-q` shall increase along the positve x-axis

Assertion: Two charges q_(1) and q_(2) are placed at separation r . Then magnitude of the force on each charge is F . Reason: Now a third charge q_(3) is placed near q_(1) and q_(2) . Then force on q_(1) and q_(2) remains F .
