The Figure Shows the Orientation of a Flat Circular Loop $\theta$

Multiple Choice

The figure shows the orientation of a flat circular loop consisting of 50 closely wrapped turns each carrying a current I.The magnetic field in the region is directed in the positive z direction and has a magnitude of 50 mT.The loop can turn about the y axis.If $\theta$ = 20 $\degree$ ,R = 0.50 m,and I = 12A,what is the magnitude of the torque exerted on the loop?

A) 8.1 N . m
B) 24 N . m
C) 22 N . m
D) 13 N . m
E) 16 N .. m
