A wire of length l , mass m and resistance R slides without any friction down the parallel conducting rails of negligible resistance . The rails are connected to each other at the bottom by a resistanceless rail parallel to the wire so that the wire and the rails form a closed rectangualr conducting loop. The plane of the rails makes an angle theta with the horizontal and a uniform vertical magnetic field of the inducetion B exists throughout the rregion. Find the steady state velocity of the wire.
