A single circulаr lооp оf wire of rаdius 10 cm cаrries a current of 10 mA in a counter-clockwise direction when viewed from above. The loop is in a uniform magnetic field that has a magnitude of 8.00 X 10-5 T{"version":"1.1","math":"8.00 X 10-5 T"} and makes an angle of 60° with the plane of the loop. What is the magnitude of the torque on the loop?
