Questions

Two long, smooth, horizontal metal rails, 0.50 m apart, lie in a uniform vertical magnetic field of 0.80 T. At one end they are joined by an uncharged capacitor of 0.50 F. A metal rod of mass 0.20 kg lies across the rails, as in the figure, and is given a push so that it starts sliding away from the capacitor at 7.0 m/s. No other force acts along the rails. The rod and rails together have a resistance of 2.0 Ω. How much heat is produced in the circuit in all, by the time the current has stopped?
