Question

Two parallel rails with negligible resistance are 10.0 cm apart and are connected by a resistor of resistance R₃=5.00Ω . The circuit also contains two metal rods having resistances of R₁= 10.0 Ω and R₂ = 15.0 Ω sliding along the rails (Fig. P31.31). The rods are pulled away from the resistor at constant speeds of v₁= 4.00 m/s and v₂= 2.00 m/s, respectively. A uniform magnetic field of magnitude B =0.0100 T is applied perpendicular to the plane of the rails. Determine the current in R₃.
