JEE MAIN 2024

31.01.24 S2

Question

A uniform magnetic field of $2 \times 10^{-3} \mathrm{~T}$ acts along positive Y -direction. A rectangular loop of sides 20 cm and 10 cm with current of 5 A is $\mathrm{Y}-\mathrm{Z}$ plane. The current is in anticlockwise sense with reference to negative X axis. Magnitude and direction of the torque is

Select the correct option:

$2 \times 10^{-4} \mathrm{~N}-\mathrm{m}$ along positive z -direction

$2 \times 10^{-4} \mathrm{~N}-\mathrm{m}$ along negative $Z$-direction

$2 \times 10^{-4} \mathrm{~N}-\mathrm{m}$ along positive X -direction

$2 \times 10^{-4} \mathrm{~N}-\mathrm{m}$ along positive Y -direction
