6. A conducting bar moves along frictionless conducting rails connected to a 4.00- resistor as shown in the figure. The length of the bar 1.60 m and a uniform magnetic field of 2.20 T is applied perpendicular to the paper pointing outward, as shown. (a) What is the applied force required to move the bar to the right with a constant speed of 6.00 m/s? (b) At what rate is energy dissipated in the 4.00 2 resistor?
