Stationary Electron accelerated through potential difference

[dr.mt]

I have this question that asks what the velocity of the stationary electron is after being accelerated by potential difference. The potential difference is 500v, but the specific potential difference doesn't concern me. I'm uncertain of how i get the velocity, because i don't know an equation for velocity affected by potential difference. i feel as though this is incredibly simple and I'm missing something.

Do you know what the energy might be?

Wow, second time today.

Zz.

Oh alright, yep simple mistake. it'd be qV=(mv^2)/2 converted to veloctiy= (2qV/m)^(1/2) right?

Thank you ZapperZ. v^2= 2eV/m
