A conducting rod of mass m is placed in contact with two long conducting rails placed parallel with a distance L between them The resistance of the rod and the rails is negligible Two ends of the rails are connected by a wire of resistance R and the whole setup lies on an insulating horizontal surface A uniform magnetic field of intensity B exists in a direction perpendicular and into the plane of the paper At t 0 the rod is given a velocity v perpendicular to its length as shown The rod moves on the rails without friction At subsequent time instants
