As shown in the figure, a straight conductor parallel to the x axis can slide without friction along the top of two horizontal conductor rails that are parallel to the “y” axis and at a distance of L = 0.30 m apart, in a magnetic field 1 T. A current is maintained through the conduit of 32 A. If a rope is tied to the center of the conductor, it passes through a frictionless pulley, what mass m suspended from the rope allows the conductor to be at rest?
