comment An alternate approach to find variation of gravitational acceleration with respect to depth of an object in Earth
I think it is more a mathematical problem like this. But you can only approximate them as point particles in the far field limit. You will have to integrate the forces itself, i.e., the y-componentn of the 1/r^2. You see why people like the spherical shell approach?
