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 center 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:

A

`3xx10^-3 N m`

B

`1.5 xx 10^-3 N m`
