Two parallel resistanceless rails are connected by an inductor of inductance L at one end as shows in Fig. A magnetic field B exists in the space which is perendicular to the plane of the rails. Now a conductor of length l and mass m is placed transverse on the rail and given an inpulse J toward the rightward direction. Then choose the correct option (S).
