The Track lies in a vertical uniform magnetic field of maA metal wire of mass m=24.1 mg can slide with negligible friction on two horizontal parallel rails separated by distance d= 2.56 cm.gnitude 56.3 mT. At time t=0 device G is connected to the rails, producing a constant current i=9.13mA. At t=61.1ms what is the speed and direction of the wire?
