A Loop Is Pulled with a Force F to the Right

Multiple Choice

A loop is pulled with a force F to the right to maintain a constant speed of 8.0 m/s.The loop has a length of 0.15 m,a width of 0.080 m,and a resistance of 200.0 .At the instant shown,the loop is partially in and partially out of a uniform magnetic field that is directed into the paper.The magnitude of the field is 1.2 T.

-Determine the magnitude of the force required to pull the loop.
