A metal rod with length 4 meter and resistance 57 milliohm is sitting on a U- shaped rail under the influence of uniform magnetic field (0.05 Tesla). Assume that magnetic field is perpendicular to the plane of rails. How much force one have to apply to keep the rod moving at a constant speed of 0.6 m/s?
