$List-II$ gives the torques experienced by the circular loop at time $t=\frac{\pi}{6 \omega}$, Let $\alpha=\frac{A^2 \mu_0^2 m^2 I^2 \omega}{2 R}$.
| $List-I$ | $List-II$ |
| ($I$) $\frac{1}{\sqrt{2}}(\sin \omega t \hat{j}+\cos \omega t \hat{k})$ | ($P$) $0$ |
| ($II$) $\frac{1}{\sqrt{2}}(\sin \omega t \hat{j}+\cos \omega t \hat{k})$ | ($Q$) $-\frac{\alpha}{4} \hat{i}$ |
| ($III$) $\frac{1}{\sqrt{2}}(\sin \omega t \hat{j}+\cos \omega t \hat{k})$ | ($R$) $\frac{\alpha}{4} \hat{j}$ |
| ($IV$) $\frac{1}{\sqrt{2}}(\sin \omega t \hat{j}+\cos \omega t \hat{k})$ | ($S$) $\frac{\alpha}{4} \hat{j}$ |
| ($T$) $-\frac{3 \alpha}{4} \hat{i}$ |
