A conducting bar moves along frictionless conducting rails connected to a 4.0 Ohm resistor. The length of the bar is 1.6 m and a uniform magnetic field of 2.2 T is applied perpendicular to the paper, pointing outward. 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 4.0 Ohm resistor?
