<p>Newton’s universal law of gravitation states that the gravitational force between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers. Mathematically represented as $F = G \rac{M_1 M_2},{d^2}$, where $F$ is the gravitational force, $M_1$ and $M_2$ are masses of two objects, $d$ is the distance between the center of two objects, and $G$ is the gravitational constant.</p> Signup and view all the answers

<p>Let us consider two objects having masses $M_1$ and $M_2$ and they are separated by distance $d$. Let $F$ be the gravitational force between their centers. According to Newton’s universal law of gravitation, $F = G \rac{M_1 M_2},{d^2}$.</p> Signup and view all the answers
