It does not depend on the nature of the medium in which the bodies are kept.

Vedclass · Answer

(D) According to Newton's law of gravitation,the force between two masses $M_1$ and $M_2$ separated by a distance $r$ is given by $F = \frac{G M_1 M_2}{r^2}$.Rearranging for $G$,we get $G = \frac{F r^2}{M_1 M_2}$.$G$ is a universal constant,meaning its value does not depend on the masses,the distance between them,or the nature of the medium in which the bodies are placed.Since $G$ is a physical constant with dimensions $[M^{-1} L^3 T^{-2}]$,it has specific units (e.g.,$N \cdot m^2/kg^2$ in $SI$ units) and its numerical value changes depending on the system of units used.Therefore,the statement that it does not depend on the nature of the medium is correct.
