Answer 1

Two objects are kept at a distance of d from each other. The gravitational force between them is proportional to $\sf\dfrac{1}{d^2}$.

❖ The magnitude of gravitational force between two point masses is directly proportional to the product of masses and inversely proportional to the square of the distance between them.

• This is known as newton's law of gravitation.

$\dag\:\underline{\boxed{\bf{\orange{F=\dfrac{Gm_1m_2}{d^2}}}}}$

Where d denotes distance between two objects.

» Gravitational force follow the inverse-square law and it is always attractive in nature.

» The law of gravitation is strictly true for point masses.

» The value of G doesn't depend on the nature and size of the masses.

» The law of gravitation is universally valid. It applies to small objects on the earth, planets in the solar system and to galaxies.
