A rod of mass 0.720 kg and radius 6.00 cm rests on two parallel rails that are d = 12.0cm apart and L = 45.0cm long. The rod carries a current of I = 48.0 A in the direction shown and rolls along the rails without slipping. A uniform magnetic field of magnitude 0.240 T is 2 | Page directed perpendicular to the rod and the rails. If it starts from rest, what is the speed of the rod as it leaves the rails?
