A conducting rod of length 1=1,0 m is free to slide between two vertical copper tracks. A constant magnetic field of B=9,0 T is directed perpendicular to the axes of the copper tracks, as shown in the
figure. Under the effect of gravitation force, the rod moves with a terminal velocity of v=5,7 m/s. The resistance of the
external resistor is 5 ohm. Calculate the current on the resistor.​
