A conducting rod of mass
slides along a pair of conducting rails which are separated by a distance
. Gravity is acting vertically downward direction. A series combination of a resistor
and an inductor
completes the circuit. There is an ambient magnetic flux density
which points into the page.
Initially, the rod has zero speed and there is no current in the circuit.
If the magnitude of maximum velocity attained by rod over all time is
.
If the magnitude of minimum velocity attained by rod over all time is
.
