I Understanding gravitational potential due to spherical shell

  1. Aug 27, 2016 #1
    I know that gravitational potential due to uniform sherical shell at a point outside the shell is equivalent to the potential due to particle of same mass situated at the centre and got proof here http://m.sparknotes.com/physics/gravitation/potential/section3.rhtml. But I was looking for more intuitive proof. Can anyone help me? It really bother me.

    For some values of "intuitive", Gauss' Law might do.

    https://en.m.wikipedia.org/wiki/Gauss's_law_for_gravity

    Short version is that the integral of the gravitational flux over the surface of some volume depends only on the enclosed mass. If you have a spherically symmetric mass distribution and consider the surface of a concentric spherical volume then the answer drops out in a couple of lines (hint: in this case, ##\vec g.d\vec A=gdA##).
