# Net Gravitational Force

Hi,

I attached a diagram... to find out the arrangement of the magnitude of the net gravitational force on the particle labeled m from the smallest to the biggest.

my answer is A B D C, anyone had a different way of looking at it?
could you explain? some of my friends said it was A D B C... =|

In D, there is one mass at distance d, the other at distance $\sqrt{d^2+ D^2}$.
The force from the mass at distance D will be greater than the force from the mass a distance $\sqrt{d^2+ D^2}$ so the net force in B is greater than in D.
