Photon mass

  1. May 6, 2007 #1

    I have this question, I need your help:

    If the photon had mass "m" , show that the Gauss' law would no longer be true.
    Note that the electric poential for a point charge would then have a form
    V(r) = e/r exp ( -mc/h * r )

    Thank you

    Just find E=-grad\phi and show that the Gauss ilntegral for that E varies with
    the radus of the sphere.
