Need to know

What you need to know

  • 18.2 Uniform electric fields.
  • E is now also defined by the units Vm -1.
  • The equation above can only be used for two charged parallel plates.
  • A charged particle will move through an electric field due to a force on it that is caused by said electric field.
  • The trajectory, as shown in the diagram above is parabolic .
  • The direction of parabola depends on the charged of the particle.
