Do you understand the gravity of the matter?

Classical Mechanics Level 3

Two identical spheres of identical density and radius R R touch each other. Suppose the total mass of the spheres can vary (while maintaining the original density), how does the force of attraction between them depend on R R ?

R − 4 \color{#3D99F6}R^{-4} R 4 \color{#3D99F6}R^{4} R − 2 \color{#3D99F6}R^{-2} R 2 \color{#3D99F6}R^{2}

As density is fixed, M is proportionate to R^3. Now, F=G.M^2/R^2=G.R^6/R^2=G.R^4

Ah i confused R with the distance between the balls, not their radius
