A closely wound solenoid of 2000 turns and area of cross-section `1.5xx10^(-4)m^(2)` carries a current of 2.0 a. it suspended through its centre and perpendicular to its length, allowing it to turn in a horizontal plane in a uniform magnetic field `5xx10^(-2)` tesla making an angle of `30^(@)` with the axis of the solenoid. The torque on the solenoid will be:

B. `1.5xx10^(-3)N-m`
C. `1.5xx10^(-3)N-m`
D. `3xx10^(-2)N-m`
