Two identical bar magnets are fixed with their centres at a distance d apart. A stationary charge Q is placed at P in between the gap of the two magnets at distance D from the centre O as shown in the figure. The force on the charge Q is

A

zero

B

directed along `OP`

C

directed along `PO`

D

directed perpendicular to the plane of paper

Text Solution

Verified by Experts

The correct Answer is:
A
Magnetic field due to bar magnets exerts force on moving charges only. Since the charge is at rest, zero force acts on it.
