Indicate whether the statement is true or false
Torque: In the figure, the rectangular loop is pivoted about one side (of length 0.060 m), that coincides with the y-axis. The end (length 0.020 m) of the loop that lies in the xz-plane makes an angle of 37° with the x-axis as shown. The loop carries a current of I = 69 A in the direction shown. (In the side of the loop that is along the y-axis the current is in the +y direction.) If there is a uniform magnetic field of magnitude 9.7 T in the -x direction, find the magnitude of the torque that this magnetic field exerts on the loop.
