Consider the arrangement shown in the figure below where R = 5.50 Ω, ℓ = 1.40 m, and B = 2.25 T. a) At what constant speed (in m/s) should the bar be moved to produce a current of 1.10 A in the resistor? b) What power (in W) is delivered to the resistor? c) What magnetic force (in N) is exerted on the moving bar? (Enter the magnitude.) d) What instantaneous power (in W) is delivered by the force Fapp on the moving bar?
