A rectangular coil of length $\displaystyle 0.12$ m and width $\displaystyle 0.1$ m having $\displaystyle 50$ turns of wire is suspended vertically in a uniform magnetic field of strength $\displaystyle 0.2$ Weber/$\displaystyle \mathrm{m}^2$. The coil carries a current of $\displaystyle 2$ A. If the plane of the coil is inclined at an angle of $\displaystyle 30$° with the direction of the field, the torque required to keep the coil in stable equilibrium will be :
