A Flat Square Coil of Wire Measures $9.5 \mathrm {~cm}$ On Each Side and Contains 175 Turns of Very Thin

A flat square coil of wire measures $9.5 \mathrm {~cm}$ on each side and contains 175 turns of very thin wire. It carries a current of $6.3 \mathrm {~A}$ in a uniform 0.84-T magnetic field. What angle less than $90 ^ { \circ }$ should the plane of this coil make with the magnetic field direction so that the magnitude of the magnetic torque on it is $6.5 \mathrm {~N} \cdot \mathrm { m }$ ?
