Solution

The correct option is D - $\to F$
The force on the two arms parallel to the field is zero( since $\to d l \times \to B = 0$
$∴$ Force on remaining arms $= - \to F$ since current direction changes for this arm.

A square current carrying loop is suspended in a uniform magnetic field acting in the plane of the loop. If the force on one arm of the loop is →F, the net force on the remaining three arms of the loop is

The correct option is D -→FThe force on the two arms parallel to the field is zero( since →dl×→B=0∴ Force on remaining arms =−→F since current direction changes for this arm.
