Answer:

Explanation:
For a charged particle accelerated by an electric field, the kinetic energy gained by the particle is equal to the decrease in electric potential energy of the particle; therefore:

where
 is the final kinetic energy
 is the final kinetic energy
 is the initial kinetic energy
 is the initial kinetic energy
q is the charge of the particle
 is the potential difference
 is the potential difference
In this problem,
 is the charge of the electron
 is the charge of the electron

The electron starts from rest, so its initial kinetic energy is

Therefore,

We can write the final kinetic energy of the electron as

where
 is the electron mass
 is the electron mass
v is the final speed
And solving for v,
