A pair of parallel horizontal conducting rails of neglig ble resistance shorted at one end is fixed on a smooth table The distance between the rails is L A massless conducting rod of resistance R can slide on the rails frictionlessly The rod is tied to a massless string which passes over a pulley fixed to another edge of the table A mass m tied to the other end of the string hangs vertically A constant magnetic field B exists along the perpendicular to the plane of the table in upward direction If the system is released from rest calculate 1 the terminal velocity of the rod il the acceleration of the mass at the instant when the velocity of the rod is half the terminal velocity Z
