A rod of mass `m` and radius `R` rest on two parallel rails that are distance `l` apart and have a length `L`. The rod carries a current `I`( in the direction shown ) and rolls along the rails without slipping. A uniform magnetic field `B` is directed perpendicular to the rod and the rails. If it starts from rest, wat is the speed of the rod as it leaves the rails ?

A rod of mass 0.720 kg and radius 6 cm rests on two parallel rails that are d=12 cm apart and length of rails is L=49 cm. The rod carried a current of I=48 A Fig. and rolls along the rails without slipping. A uniform magnetic field of magnetude 0.240 T is 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?

A conducting rod MN of mass m and length 'l' is placed on parallel smooth conducting rails connected to an uncharged capacitor of capacitance C and a battery of emf epsilon as shown. A uniform magnetic field B is existing perpendicular to the plane of the rails. The steady state velocity acquired by the conducting rod MN after closing switch S is (neglect the resistance of the parallel rails and the conducting rod)
