An electron, being a charged body, is acted on by a force, and is therefore
accelerated, when immersed in an electric field. If you really want to be cruel,
you attach numbers to the whole situation and hand it to someone to solve.
The kinetic energy of a moving electron is
KE = (Lorentz factor - 1) x (rest-masselectron) x c2
Lorentz factor = [sqrt( 1 - v2/c2 )]-1
KE107 m/s = (4.5588 x 10-17 Joule) / (1.6 x 10-19 eV/J ) = 284.9 electron-volts
So you need 285 volts between the plates in order to have the electrons moving
as fast as you want them when they hit the positive plate.
I'm sure there had to be an easier way to do this.

If an electron gun electron is moved with electric potential of 9000 volt.then What will be the energy of electron in electron volt?
If an initially stationary electron falls through 9,000 volts of potential difference, then it arrives at the positive terminal with 9,000 eV of energy.
What is an electron vault?
1 electron-volt is a small unit of energy. It's the amount of energy gained or lost by the (amount of electric charge on one electron) moving through a (potential difference of one volt). 1 joule of energy is the same as about 6,241,400,000,000,000,000 electron-volts.
An electron starting from rest accelerates through a potential difference of 388 V What is the final de Broglie wavelength of the electron assuming that its final speed is much less than the spee?
An electron, starting from rest, accelerates through a potential difference of 417 V.
What is the difference between an electron donor and electron acceptor?
Donor atoms are atoms that donate electrons and have an extra pair of electrons in their orbital. Acceptor atoms are atoms that accept electrons and have a empty orbital to accommodate the extra electrons.
What are the four essential elements required for x-ray production?
a target, a vacuum, an electron source and a high potential difference

Does an electron accelerate greater than a proton in an electric field?
yes, it has less mass.
In physics what is an electron volt?
In physics an electron volt is a very small unit of energy. An electron volt is the amount of energy gained by the charge of an electron once it has moved across an electric potential difference of one volt.
Why electron leave conduction band?
When an electric field is applied to accelerate them or when the temperature of the crystal is raised.
What is the difference between electron flow direction and electric current flow direction?
the electrons flow from the region of low potential to region of high potential. the electric current also flow in this direction but for convention we took it as the flow of positive charge from region of low to high region potential.
Do electron moves up or fall down a potential gradient?
The potential gradient gives the electric field intensity E at point in electric field which is directed from high to low potential. An electron being a negative charge particle therefore will tend to move from low potential to high potential, hence will move up the electric field
How can electric potential be high when electrical potential energy is realitively low?
Electric potential can be high when electrical potential energy is relatively low if the charge is low as well. ... It is correct to say that an object with twice the electric potential of another has twice the electrical potential energy only if the charges are the same.
