Problem

A proton (mass

1.67\times10^{-27}\,\text{kg}

, charge

+1.60\times10^{-19}\,\text{C}

) is accelerated from rest through a potential difference of

3.0\,\text{kV}

. Determine its speed after this acceleration, and state whether it is moving toward a region of higher or lower electric potential.
