In both the force equation F=qvB and the radius equation r=mv/qB, v refers to the velocity of the electron.
How do you calculate the speed of an electron?
The speed of electrons
- The mass of the electron is m = 9 × 10 -31 kg.
- The electronic charge is e = 1.6 × 10 -19 C.
- For an electron gun with a voltage between its cathode and anode of V = 100V the electron will have a speed of about v = 6 × 10 6 m/s. (Relativistic effects have not been taken into account.)
What is electron velocity?
In physics, a drift velocity is the average velocity attained by charged particles, such as electrons, in a material due to an electric field. In general, an electron in a conductor will propagate randomly at the Fermi velocity, resulting in an average velocity of zero.
