Question

the law of gravitation gives the gravitational force between
​

Answer 1

Answer:

Newton's law of universal gravitation states that every point mass in the universe attracts every other point mass with a force that is directly proportional product of their masses and inversely proportional to the square of the distance between them .

Answer 2

Question :

• The law of gravitation gives the Gravitational force between _________

Answer :

• Every Point Mass In The Universe Attracts Every Other Point

Newton's Gravitational Law :

• This law states that every particle of matter in this universe attracts every other particle with a force.

• This force is directly proportional to the product of their masses and inversely proportional to the square of the distance between the centres of these masses.

• The direction of the force acts along the line joining the masses.

• The force between the masses is always attractive and it does not depend on the medium where they are placed.

Let, $\bf{m_1\:and\:m_2}$ be the masses of two bodies A and B placed r metre apart in space.

Force F ∝ $\bf{m_1 × m_2}$

F ∝ $\dfrac{1}{r²}$

On combining the above two expressions

F ∝ $\dfrac{m_1 × m_2}{r²}$

F = $\dfrac{Gm_1 × m_2}{r²}$

Where G is the universal gravitational constant.

Its value in SI unit is 6.674 × $\bf{10}^{-11}$ Nm² $\bf{kg}^{-2}$
