I Inverse Square Law and various space dimensions

  1. Apr 5, 2016 #1
    I am interested in the derivation of the inverse square law in various dimensions via Green's functions. I think the trick is to imagine a sphere and then to integrate over it. Does anyone know a book or notes where this is explained?

    I found this below from here, but could not really understand what's going on:


    Is this some theorem that connects the two integrals (Green's theorem possibly?) in (1.7)?
