lets consider a regular hexagon of side length 'a' on a plane with its vertices named A,B,C,D,E and F. Let there are six identical particles each of mass M fixed at the vertices of this hexagon. Lets take a straight line passing through the center of the hexagon and perpendicular to the plane of hexagon as axis of the hexagon now two particles (one at B and the other at E ) are removed, and a article of mass m is placed on the axis of the hexagon and released. What can be its maximum acceleration due to gravitational force of masses at the vertices?
