A rectangular coil of length 0.12 m and width 0.1 m having
50 turns of wire is suspended vertically in a uniform
magnetic field of strength 0.2 Weber/m2. The coil carries a
current of 2A. If the plane of the coil is inclined at an angle
of 300 with the direction of the field, the torque required to
keep the coil in stable equilibrium will be
