Three spheres are kept in such a way that they form an eqilateral triangle.

Using Newton's Law of gravitation,

F= GmM/r²

F=G(R/3)²/(m/2+m/2)²........(Radius gets added)

F=GR²/9../M²

Using Resultant formula

√[F² + F² + 2ABcos●]

√[F² + F² + 2F²cos60]

= √3F²

⁼√3GR²/9.../M²

Can be simplified further......
