Problem

A singly charged ion of mass

3.2\times10^{-26}\,\text{kg}

starts from rest and is accelerated through a uniform potential difference until its speed is

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

. What is the magnitude of the potential difference? a)

7.2\times10^{4}\,\text{V}

1.8\times10^{4}\,\text{V}

3.6\times10^{4}\,\text{V}

3.6\times10^{3}\,\text{V}
