question 32

Multiple Choice

In the arrangement shown, a conducting bar of negligible resistance slides along horizontal, parallel, frictionless conducting rails connected as shown to a 2.0- $\Omega$ resistor.A uniform 1.5-T magnetic field is perpendicular to the plane of the paper.If L = 60 cm, at what rate is thermal energy being generated in the resistor at the instant the speed of the bar is equal to 4.2 m/s?

• A)8.6 W
• B)7.8 W
• C)7.1 W
• D)9.3 W
• E)1.8 W
