Question

In the figure, the rolling axle, 1.58 m long, is pushed along horizontal rails at a constant speed v = 3.03 m/s. Image: http://s1148.photobucket.com/albums/o575/sarahjoy1216/?action=view&current;=Screenshot2012-07-17at101516AM.png A resistor R = 0.460 ? is connected to the rails at points a and b, directly opposite each other. The wheels make good electrical contact with the rails, and so the axle, rails, and R form a closed-loop circuit. The only significant resistance in the circuit is R. There is a uniform magnetic field B = 7.30

Explanation / Answer

V = I R = 0.460 * 0.76 = 0.350 V
