FIGURE 29-13 -A Conducting Bar Moves Along Frictionless Conducting Rails Connected to Rails

question 105

Short Answer

FIGURE 29-13
-A conducting bar moves along frictionless conducting rails connected to a 4.00-Ω resistor as shown in Fig. 29-13. The length of the bar is 1.60 m and a uniform magnetic field of 2.20 T is applied perpendicular to the paper.
(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 Ω resistor?
