An electron and a proton are each placed at rest in an electric field of 337 N/C.
What is the velocity of the electron 57.1 ns
after being released? Consider the direction
parallel to the field to be positive. The fun-
damental charge is 1.602 x 10-19 C, the mass
of a proton is 1.67267 x 10-27 kg and of an
electron 9.109 x 10-31 kg.
Answer in units of m/s.
