Answer the following
In the arrangement shown, a conducting bar of negligible resistance slides along horizontal, parallel, friction-less conducting rails connected as shown to a 4 ohm resistor (use this value. Ignore the 2.0 ohm mentioned in the figure for the resistance). A uniform 1.7-T magnetic field is perpendicular to the plane of the paper. If L = 51 cm, at what rate is thermal energy being generated in the resistor at the instant the speed of the bar is equal to 4.8 m/s? 2.02 L.
