Multiple Choice

FIGURE 23-11
-A conducting bar moves along frictionless conducting rails connected to a 4.00-Ω resistor as shown in Figure 23-11. The length of the bar is 1.60 m and a uniform magnetic field of 2.20 T is applied perpendicular to the paper. An applied force moves the bar to the right with a constant speed of 6.00 m/s. At what rate is energy dissipated in the 4.00 Ω resistor?

• A) 60 W
• B) 121 W
• C) 21.2 W
• D) 112 W
• E) 11.5 W
