x X X X X X X XX B in X X X X X X X X X X X X X X X X X X XX X X X x X X X X X X xx xx app XX 15. M Figure P23.15 shows a top view of a bar that can slide on two fric- tionless rails. The resis- R X F. tor is R = 6.00 12, and a 2.50-T magnetic field is directed perpendicu- larly downward, into the Figure P23.15 Problems 15 paper. Let l = 1.20 m. through 18. (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?
