If we try to imagine how things would be if electric force were not a pure inverse square force but instead a force with finite range, for instance, a force varying like $$e^{-\lambda r}\over r^2$$, ...
Then it goes on explaining how Gauss law would fail because for a very large surface, E field would be vanish with flux through it and though we can calculate div for this field it won't depend on source density.
But I don't get what makes this particular function so evil that it would break physics, I can see that fallout rate is exponentially large for this function than would for a "pure inverse relationship".
Basically I want to know what makes this function so different than the ##1/r^2## relationship ?
