In the figure, the rod is moving to the right with a speed of
1.3 m/s and has a resistance of 2.5 Ω. the rail spacing is l=25cm.
the magnetic field is 0.35 T and the resistance of the U-shaped
conductor is 25 Ω at a given instant. Calculate a) the induced emf,
b) the current in the U-shaped conductor, and c) the external force
needed to keep the speed of the rod constant at this instant.
