In the sketch, a bar is moving to the right at constant speed of 30.0 m/s in a uniform magnetic field of 8.0 T directed into the page. The resistance R is 6.0 Ω. The separation L between the rails is 3.0 m. The bar slides with no friction while making continuous electrical contact with the rails. Find the power released on the resistor R (ignore the resistance of the rails and the slider)
