1. What do these results tell you about how these forces affect the electron?

  • The strength of the force of gravity is always stronger than the strength of an electric field.
  • The electron would accelerate faster towards the electric field because the force and therefore acceleration is greater (F = ma)
  • The strength of an electric field is always stronger than the force of gravity.
  • The electron would keep falling due to gravity even if it was in an electric field.
