Let’s catch some speedy electrons! 🚀 These tiny particles are like the Usain Bolts of the subatomic world, and we’re here to help you calculate their velocities in the most electrifying way possible!

Formula for Electron Speed:

v = e * E / (m * c)

Where:

  • v is the speed of the electron.
  • e is the elementary charge.
  • E is the electric field strength.
  • m is the mass of the electron.
  • c is the speed of light.
