Gauss' law (1/r^3 instead of 1/r^2)

  1. Dec 27, 2007 #1
    1. The problem statement, all variables and given/known data
    If the electric field of a point charge were proportional to 1/(r^3) instead of 1/(r^2), would Gauss's law still be valid? Explain reasoning.


    2. Relevant equations

    3. The attempt at a solution
    Considered a spherical Gaussian surface centered on a single point charge.

    How would the flux through a sphere of radius one centered on the charge compare with the flux through a sphere of radius two?

    What is true of the entire sphere is also true of any portion of its surface, I believe...
