Which law governs the intensifying gravitational pull as a collapsing knot gathers more mass?

Answer

Inverse square law of distance, $F_g=G M_1 M_2/d^2$

The gravitational attraction within the collapsing cloud increases according to the inverse square law of distance, meaning the pull intensifies dramatically as the mass concentrates.
