A closely wound solenoid of `2000` turns and area of cross-section `1.5 xx 10^(-4) m^(2)` carries a current of `2.0 A`. It is suspended through its centre and perpendicular to its length, allowing it to turn in a horizontal plane in a uniform magnetic field `5 xx 10^(-2)` tesla making an angle of `30^(@)` with the axis of the solenoid. The torque on the solenoid with the
