Two parallel rails with negligible resistance are 10.0 cm
Chapter 31, Problem 37(choose chapter or problem)
Two parallel rails with negligible resistance are 10.0 cm apart and are connected by a resistor of resistance R3 5 5.00 V. The circuit also contains two metal rods having resistances of R1 5 10.0 V and R2 5 15.0 V sliding along the rails (Fig. P31.37). The rods are pulled away from the resistor at constant speeds of v1 5 4.00 m/s and v2 5 2.00 m/s, respectively. A uniform magnetic field of magnitude B 5 0.010 0 T is applied perpendicular to the plane of the rails. Determine the current in R3.
