A closely wound solenoid of $2000$ turns and area of cross section $1.6 \times 10^{-4}m^2$, carrying a current of $4.0\;A$ is suspended through its center allowing it to turn in a horizontal plane. What are the force and torque on the solenoid, if a uniform horizontal magnetic field of $7.5 \times 10^{-2}\;T$ is setup at an angle of $30^{\circ}$ with the axis of solenoid ?
