Explanation:
C Universal law of gravitation is called the Newton's law of gravitation, it states that the gravitational force of attraction acting between two bodies of universe is
$\mathrm{F}=\frac{\mathrm{Gm}_{1} \mathrm{~m}_{2}}{\mathrm{r}^{2}}$
Where, $\mathrm{G}=$ Gravitational constant
$\mathrm{m}_{1}$ and $\mathrm{m}_{2}$ are the masses of the objects $\mathrm{r}=$ the distance between them
Hence, it is also known as inverse square law where force is inversely proportional to the square of the distance between the bodies.
