State the Universal law of gravitation. At which point on the surface of
earth will the gravitational force on a body is more?
Answers
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.
In combination, the equatorial bulge and the effects of the surface centrifugal force due to rotation mean that sea-level gravity increases from about 9.780 m/s2 at the Equator to about 9.832 m/s2 at the poles, so an object will weigh approximately 0.5% more at the poles than at the Equator.

Explanation:
The gravitational force between any two bodies having some mass can be determined from Newton's law of gravitation.
The force of attraction between bodies is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

Here, G is called the universal gravitational constant.
In combination, the equatorial bulge and the effects of the surface centrifugal force due to rotation mean that sea-level gravity increases from about 9.780 m/s2 at the Equator to about 9.832 m/s2 at the poles, so an object will weigh approximately 0.5% more at the poles than at the Equator.
