A rectangular coil (Dimension $\displaystyle 5 \mathrm{~cm} \times 2.5 \mathrm{~cm}$ ) with $\displaystyle 100$ turns, carrying a current of $\displaystyle 3$ A in the clock-wise direction, is kept centered at the origin and in the X-Z plane. A magnetic field of $\displaystyle 1$ T is applied along X-axis. If the coil is tilted through $\displaystyle 45$° about Z-axis, then the torque on the coil is :
