Find the drift velocity of charge carriers producing a current of

1\ \text{A}

in a copper conductor of cross-sectional area

1\ \text{cm}^2

and length

10\ \text{km}

. The free-electron density of copper is

8.5 \times 10^{28}\ \text{m}^{-3}

. How long will the charge take to travel from one end of the conductor to the other?
