A Loop Is Pulled with a Force F to the Right

question 20

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 $\varOmega$ . 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.
