In Figure, the rod has a resistance R and the rails have negligible resistance. A capacitor with charge Q0 and capacitance C is connected between points a and b such that the current in the rod is downward. The rod is placed at rest at t = 0.

(a) Write the equation of motion for the rod on the rails.

(b) Show that the terminal speed of the rod down the rails is related to the final charge on thecapacitor.
