A Loop with a Resistance of 4

question 58

Multiple Choice

A loop with a resistance of 4.0 is pushed to the left at a constant speed of 2.0 m/s by a 24 N force.At the instant shown in the figure,the loop is partially in and partially out of a uniform magnetic field.An induced current flows from left to right through the resistor.The length and width of the loop are 2.0 m and 1.0 m,respectively.

-At what rate is energy dissipated by the resistor?

• A)130 W
• B)96 W
• C)32 W
• D)49 W
• E)8.0 W
