Deflection of charged particles in an electric field

Demonstration of electrons moving through an electric field and being deflected along a parabolic path. The experimental set up includes an evacuated chamber, cathode filament to produce electrons by thermionic emission, electric plates for accelerating the electrons, parallel charged plates to produce the uniform electric field, EHT power supplies and a fluorescent screen for tracing path of electrons through the field.
Coming soon … charged particles moving in a magnetic field and the veloctiy selector.

Relevant concepts: electrostatics, electric fields, electrons, and resultant motion of uniform acceleration superimposed onto perpendicular constant velocity vector.

nice hands

Thanks, they’re insured.

[@dimitryanyanwu7681]

Can you please 🙏 explain this experiment more?

[@PhysicsHQ]

Does the below help? If not reply with what you’d like further explanation of.
1. The charged particles used in this experiment were electrons.
2. Electrons are accelerated horizontally by use of an electric field.
3. After acceleration they enter an electric field that is applied vertically.
4. Electrons are attracted toward the positive plate and repelled by the negative plate. This gives rise to an electric force on the electrons that acts vertically on the electrons.
5. As a consequence of the vertical electric force and incoming velocity the electrons are deflected to follow a parabolic path.
6. The video demonstrated the effect of increasing and decreasing the electric field strength.
7. It also demonstrated the effect of increasing and decreasing the accelerating field for a constant deflecting field strength.
