Question

state the univetsal law of gravitation​

Answer 1

Question :

• State The Univetsal Law Of Gravitation

Answer :

• 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  $\bf{kg^-2}$

Answer 2

Answer:

Newton's law of gravitation, statement that any particle of matter in the universe attracts any other with a force varying directly as the product of the masses and inversely as the square of the distance between them.

Universal Gravitation Equation

F is the gravitational force between bodies. m1 is the mass of one of the objects. m2 is the mass of the second object. r is the distance between the centres of two objects. G is the universal gravitational constant.
