A conductor of mass 0.720 kg
rests on two parallel rails as in
the figure that is d=12.0 cm
apart and L=45.0 cm long. The
conductor carries a current of
I=51.1 A in the direction shown
and can slide frictionlessly. A
uniform magnetic field of
magnitude 1.7 T is directed
perpendicular to the conductor
and the rails. If it starts from
rest, what is the kinetic energy (
in J) of the conductor as it
leaves the rails?
