53. A circular coil 0.05 m in radius, with 50 turns of wire, lies on a horizontal plane. It carries a counterclockwise current of 8.0 A. The coil is in a uniform 1.50 T magnetic field directed toward the +Y direction. Find the torque on the coil. (Given: Unit vectors î, ĵ and k̂ point in the directions of the positive X-, Y- and Z- axes and have magnitude of 1)
(A) -0.03 π î
(B) -1.50 π î
(C) 0.03 π k̂
(D) 1.5 π k̂
(E) 0.03 π ĵ
