A conductor of mass 0.720 kg rests on two parallel rails as in the figure that is d=12.0 cm apart and L=45.0 cm long. The conductor carries a current of l=D72.8 A in the direction shown and can slide frictionlessly. A uniform magnetic field of magnitude 0.6 T is directed perpendicular to the conductor and the rails. If it starts from rest, what is the kinetic energy ( in J) of the conductor as it leaves the rails?
