Answer -
Given -
- Mass of stone = 40 g = 0.04 kg
- Mass of boulder = 10 kg
- Distance b/w them = 20 cm = 0.2 m
To Find -
- Gravitational force ( in term of G i.e. universal gravitation constant )
Solution :-
We know that,
where
- G is universal gravitation constant.
- M and m are mass of two objects.
- r is the distance between them.
Substituting the values -
⇒
⇒
⇒
⇒
Gravitational force between them = 10G
