hi

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
