A conducting rod is free to slide on two parallel conducting bars. A resistor is connected to the end of the bar. The conducting bar and the rod have negligible resistance. A constant magnetic field is directed perpendicularly into the page. The power dissipated in the resistor is 64 W. The constant speed of the rod is v=8.00 m/s. Find the magnitude of the applied force that is needed to move the rod with this constant velocity. Give your answer in N.
