A bar of mass `m` slides on a smooth horizontal conducting rail. A constant current `I` is maintained in the rod using a constant current generator as shown. There is a long straight conductor carrying current `I_(0)` parallel to the rod. Find the speed of the bar after it has travelled a distance `D`
