A Circuit Is Pulled with a 21-N Force Toward the Right

question 9

Multiple Choice

A circuit is pulled with a 21-N force toward the right to maintain a constant speed v.At the instant shown,the loop is partially in and partially out of a uniform magnetic field that is directed into the paper.As the circuit moves,a 4.0-A current flows through a 6.0- resistor.

-Which one of the following statements concerning this situation is true?

• A)The temperature of the circuit remains constant.
• B)The induced current flows clockwise around the circuit.
• C)Since the circuit moves with constant speed,the force F does zero work.
• D)If the circuit were replaced with a wooden loop,there would be no induced emf.
• E)As the circuit moves through the field,the field does work to produce the current.
