Gaussian Units: Electric Field

  1. Oct 13, 2009 #1
    I am stuck with Gaussian units. If the field in vacuum is

    [tex] E = \frac{Q}{r^2} [/tex]

    Is the field in a dielectric

    [tex] E = \frac{Q}{\epsilon_r r^2} [/tex]

    , or is it unchanged?

    The latter is the correct equation. In gaussian units, free-space epsilon is unity, this is why I prefer MKS units since all the unities in natural units sometimes hide these kind of relationships.
