Which of the following statements is /are not true about the universal gravitational constant, G                          

We know that according to the law of gravitation, the gravitational force between any two bodies that have some mass is given as:

${\text{F}}_{ }=\text{G}.\frac{{\text{m}}_{\text{1}}{\text{m}}_{\text{2}}}{{\text{r}}_{ }^2}$
Where m₁ and m₂ are the masses of the two bodies, r is the distance between them and G is the universal gravitation constant.
$G= 6.67 X {10}^{-11} N{m}^2/k{g}^2$

The value of G is constant for any two bodies involved and is independent of the medium in which the bodies lie.
We can see that it has a unit and it is not a force.
Therefore, we can say that options A and C represent incorrect statements about the gravitational constant.
