Two parallel rails with negligible resistance are 1.00E-1m apart and are connected by a 4.800 resistor. The circuit also contains two metal rods having resistances of R1=10.800 and R2=14.500 sliding along the rails (see figure). The rods are pulled away from the resistor at constant speeds v1-4.00m/s and v2=2.00m/s, respectively. A uniform magnetic field of magnitude 0.0100T is applied perpendicular to the plane of the rails. Determine the current in the 4.80ohm resistor.
