Question

State universal law of gravitation. Derive the expression for the force between two objects of masses m1 and m2 separated at a distance of d 3

​

Answer 1

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 ofG=6.67×10

−11

Nm²kg².

Answer 2

The universal law of gravitation 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 distance between them.
