Two positive charges

Q_1

and

Q_2

are fixed at

A

and

B

. A unit positive charge is taken from

A

B

along the line joining

A B

. The force experienced by unit charge

View answer and explanation

Correct option: D

Decreases first and then increases

Option D (Decreases first and then increases) is correct because the force due to Q1 decreases as the unit charge moves away, while the force due to Q2 increases as the unit charge moves closer.
