Problem

A proton (mass

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

, charge

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

) is released from rest and accelerates through a potential difference of

2.5\,\text{kV}

. Assuming non-relativistic speeds, what is the proton’s speed after the acceleration? a)

9.8\times10^{5}\,\text{m/s}

6.9\times10^{5}\,\text{m/s}

2.2\times10^{6}\,\text{m/s}

4.9\times10^{5}\,\text{m/s}
