Question

Find the gravitational force between two stones of mass 1 kg each separated by a distance of

1m in vacuum.​

Answer 1

Given :-

Mass = 1 kg

Distance separated = 1 m

To Find :-

The gravitational force between two stones.

Analysis :-

Here we are given with the mass and the radius.

In order to find the force by substituting the given values in the question using the gravitational  universal law of gravitation.

Solution :-

We know that,

• f = Force
• g = Gravitational force
• m = Mass
• r = Radius

Using the formula,

$\underline{\boxed{\sf Universal \ gravitational \ force=\dfrac{GMm}{R^2} }}$

Given that,

M₁ = m₂ = 1 kg

Radius (r) = 1 m

Gravitational force (g) = 6.675 × 10⁻¹¹

Substituting their values,

$\sf f = \dfrac{6.675 \times 10^{-11} \times 1}{1}$

$\sf f=6.675 \times 10^{-11} \ N$

Therefore, the gravitational force between two stones is 6.675 × 10⁻¹¹.
