The figure below shows a top view of a bar that can slide on two frictionless rails. The resistor is R = 5.00 Ω, and a 2.50-T magnetic field is directed perpendicularly downward, into the page. Let ℓ = 1.20 m.

(a) Calculate the applied force required to move the bar to the right at a constant speed of 1.90 m/s in N (to the right).

(b) At what rate is energy delivered to the resistor in W?
