Q29: A conducting rod of length , moves on two horizontal, frictionless rails as shown in Figure P31.26. If a con- stant force of 1.00 N moves the bar at 2.00 m/s through a magnetic field B S that is directed into the page,
(a) what is the current through the 8.00-V 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 S app ?
