The figure above shows a top view of a bar that can slide without friction. The resistor is 6.00 Ω and
a 2.50 T magnetic field is directed perpendicularly downward, into the paper. Let l=1.20 m.
a. Calculate the applied force required to move the bar to the right at a constant speed of 2.00 m/s.
b. At what rate is energy delivered to the resistor?
