Question
An electron with initial speed = 2.54×10^7 m/s is traveling parallel to an electric field of magnitude = 1.66×10^4 N/C .
How far will the electron travel before it stops?
How much time will elapse before it returns to its starting point?

find its original KE.
then, work done=force*distance
where force=Eq
set them equal, solve for distance
