A uniform conducting rod with a length l=1.35m is moving to the right on two frictionless rails. A uniform magnetic field, with a magnitude of 3.00T, acts inward into the plane of the paper. In this circuit, the resistance is R=5.25Ω. 1. Determine the magnitude of the external force required to make the rod move to the right with a velocity v=2.15m/s. 2. What proportion of energy is transferred to the resistance?
