Assignment:
A conducting rod of length l moves on two horizontal, frictionless rails. If a constant force of 1.00 N moves the bar at 2.00 m/s through a magnetic field B that is directed into the page,
(a) What is the current through the resistor R?
(b) What is the rate at which energy is delivered to the resistor?
(c) What is the mechanical power delivered by the force F_app?
