A small circular loop of area $A$ and resistance $R$ is fixed on a horizontal $x y$-plane with the center of the loop always on the axis $\hat{n}$ of a long solenoid. The solenoid has $m$ turns per unit length and carries current $I$ counterclockwise as shown in the figure. The magnetic field due to the solenoid is in $\hat{ n }$ direction. $List-I$ gives time dependences of $\hat{ n }$ in terms of a constant angular frequency $\omega$.

$List-II$ gives the torques experienced by the circular loop at time $t=\frac{\pi}{6 \omega}$, Let $\alpha=\frac{A^2 \mu_0^2 m^2 I^2 \omega}{2 R}$.
