Question
The gravitational force ${F_g}$ between two objects does not depend on
✓
Answer
(a) $F_Gravitational$ $=\mathrm{F}=\left[\left(\mathrm{G} \cdot \mathrm{m}_{1} \cdot \mathrm{m}_{2}\right) / \mathrm{D}_{2}\right]$
$\mathrm{m}_{1}, \mathrm{m}_{2}$ are masses of bodies and $\mathrm{D}$ is distance between them.
$\mathrm{G}=$ Gravitational constant.
