A resistor R is connected between two parallel conducting rails separated by 30 cm, as shown in the diagram. A conducting bar maintains electric contact with the rails as it moves relative to them with constant velocity from x = 20 cm to x = 48 cm in 0.6 seconds. A uniform 0.8 T field points into the page. Calculate the induced electric potential difference between the two ends of the bar.
Two resistanceless rails rest 42 cm apart on a 6.6o ramp. They are joined at the bottom by a 0.68 Ω resistor. At the top, a copper bar of mass 0.034 kg (ignore its resistance) is laid across the rails. The whole apparatus is immersed in a vertical 0.35 T field. What is the terminal (steady) velocity of the bar as it slides frictionlessly down the rails?
