How is an electric field determined?

  1. Feb 16, 2009 #1
    I know that an electric field is a region that surrounds a charged particle and exerts a force on the particle, but I don't know how to determine an electric field.

    I am assuming you need to find the equation for the electric field?

    Remember that [tex]E=\frac{F}{q}[/tex] where F is the force felt by an electrically charged object with charge q.

    It depends on the problem being asked. Your textbook should have the equation for the electric field due to a point charge. Perhaps it also has equations for the electric fields of a line of charge as well as a charged plate or plane.

    And sometimes, the electric field is simply a given in the problem statement.
