A long piece of wire with a mass of0.160kg and total length of 4.00 m is used to make a square coil with a side of 0.100 m. The coil is hinged along a horizontal side, carries a3.06A current, and is placed in a vertical magnetic field with a magnitude of 0.0100 T.

(a) Determine the angle that the plane of the coil makes with the vertical when the coil is in equilibrium. (b) Find the torque acting on the coil due to the magnetic force at equilibrium. Nm
