two circuits, where a motional emf is induced in a metal rod moving to the right in a perpendicular magnetic field directed into the page. The velocity of the rod in Circuit 1 is two times the velocity of the rod in Circuit 2, and the induced current in Circuit 1 is two times the induced current in Circuit 2. All remaining quantities are the same in both circuits.


(a) Find the ratio emf1/emf2 of the motional emfs in the two circuits.
