FIGURE 23-9
-A conducting rod whose length is 25 cm is placed on a U-shaped metal wire that has a resistance R of 8 Ω as shown in Figure 23-9. The wire and the rod are in the plane of the paper. A constant magnetic field of strength 0.4 T is applied perpendicular and into the paper. An applied force moves the rod to the right with a constant speed of 6 m/s. What is the magnitude of the induced emf in the wire?

A) 0.2 V
B) 0.3 V
C) 0.4 V
D) 0.5 V
E) 0.6 V
