A square coil of side ‘a’ carrying current ‘ i ’ and is having one of its side AB parallel to y-axis and its plane is at angle θ = 30° with x-axis. If a uniform magnetic field B exist in the region along \[\hat{k}\] direction, then torque due to magnetic force on the coil is: Image related to
\[\frac{ia^{2}B}{2}\hat{j}\]
\[-\frac{ia^{2}B}{\sqrt{2}}\left(-\hat{k}+ \hat{j} \right)\]
\[-\frac{ia^{2}B}{2}\hat{j}\]
\[\frac{ia^{2}B}{2}\hat{i}\]
