Electric fields and forces

  1. Jan 12, 2009 #1
    So if the electrocstatic force and electric field can be different directions which direction would a particle go? Would it depend on the field or the force, or something else like potential difference?

    Why do you say that? (The direction of the force does depend on the sign of the charge.)

    Well I was reading the text book and it showed the E and the Force going different direction. I probably didnt give enough details. The particle was a test charge and was put in an already existing electric field. The force on the test charge and the field were in opposite directions.

    Was the test charge negative, by any chance?

    The direction of the (net) electric field is defined to be the direction of the force that it exerts on a positive test charge.
