A rigid rectangular loop, which measures 0.30 m by 0.40 m, carries a current of 5.5 A, as shown, A uniform external magnetic field of magnitude 2.9 T in the negative x-direction is present. Segment CD is in the x-2 plane and forms a 35 angle with the z-axis, as shown. An external torque applied to the loop keeps it in static equilibrium. The magnitude of the external torque is closest to: J= NIAB sin O ( ofz ) (1 4 ( 5 . 3 ) ( 2 . 9 ) ( sin 0.30 m B A 0.40 m B - 2.9 T A) 1.6 N . m B) 0.73 N . m C) 1.3 N . m D) 14 N .m DI.IN .m
