Two parallel rails having negligible resistance are connected by a resistor. The circuit also contains two metals rods with resistance, one with moving to the left and the other moving to the right. At t = 0 seconds the rods are 5 cm from the 6 ohm resistor. The rods are sliding along the rails and moving away from the 6 ohm resistor ar constant velocities as shown in figure below. A uniform magnetic field is...

Two parallel rails with negligible resistance are 1.00E-1m apart
and are connected by a 3.90Ω resistor. The circuit also contains
two metal rods having resistances of R1=10.70Ω and R2=14.50Ω
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
