Question

State universal law of gravitation. Derive an expression for the force of attraction between two bodies and then definite gravitational constant.​

Answer 1

Explanation:

Universal Law of Gravitation : It states that the force of attraction between two

bodies is directly proportional to the

product of their masses and inversely proportional to the square of the

distance

between them.

Let the two bodies 'A' and 'B' be of masses 'M' and 'm' respectively,

which are separated by a distance According

to Universal Law of Gravitation,

F=GM∗m²

Where, 'G' is called universal gravitation constant.

The numerical value Of G=6.67×10−¹¹Nm²kg².

Answer 2

Answer:

Explanation:

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 to the product of their masses, and inversely proportional to the square of the distance between them.
