A long current carrying wire, carrying current such that it is flowing out from the plane of paper, is placed at O. A steady state current is flowing in the loop ABCD. Then,

A

the net force is zero

B

the net torque is zero

C

as seen from O, the loop will rotate in clockwise direction along axis OO'

D

as seen from O, the loop will rotate in anticlockwise direction along axis OO'

Text Solution

Verified by Experts

The correct Answer is:
(a,c)
Net force on AB and CD will zero because magnetic field due to `I_1` is along these parts. Force on BC due to `I_1` will be outwards and on AD will be inward. This will provide clockwise torque as seen form O.
