Statement I: A resistance R is connected between the two ends of the parallel smooth conducting rails. A conducting rod lies on these fixed horizontal rails and a uniform constant magnetic field B exists perpendicular to the plane of the rails as shown in Fig. if the rod is given a velocity upsilon and released as shown in Fig. 3.188, it will stop after some time. the total work done by magnetic field negative. Statement II: If force acts opposite to direction of velocity its work done is negative.
