The lines of force of uniform magnetic field

A rectangular coil of length 20 cm, breadth 5 cm and number of turns 50 is suspended from the mid-point of its breadth and is inclined at an angle of 60^(@) with the lines of force of uniform magnetic field of 0.05 T. If 5 A current flows in the coil, what will be the torque acting on it?
