MCQ
The gravitational force ${F_g}$ between two objects does not depend on
  • ✓
    Sum of the masses
  • B
    Product of the masses
  • C
    Gravitational constant
  • D
    Distance between the masses
✓

Answer

Correct option: A.
Sum of the masses
a
(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.
