A conducting rod ab of length l, mass m and resistance R slides on a smooth, thick pair of metallic rails. The plane of the rails makes an angles theta with the horizontal. A magnetic field B acts along the perpendicular to the horizontal plane in upward direction. If the rod slides down on the rails at a constant speed v, then show that B=sqrt((mgRsintheta)/(l^(2)vcos^(2)theta)) .
