Problem

The mobility of conduction electrons in a certain metal is

4.5\times10^{-3}\,\text{m}^{2}\,\text{V}^{-1}\,\text{s}^{-1}

. If a uniform electric field of

0.10\,\text{V m}^{-1}

is applied, the drift velocity of the electrons is closest to a)

4.5\times10^{-2}\,\text{m s}^{-1}

4.5\times10^{-3}\,\text{m s}^{-1}

4.5\times10^{-4}\,\text{m s}^{-1}

4.5\times10^{-5}\,\text{m s}^{-1}
