Question

Write universal law of gravitation and derive equation of gravitation force.

​

Answer 1

Answer:

The force is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. In equation form, this is F=GmMr2 F = G mM r 2 , where F is the magnitude of the gravitational force. G is the gravitational constant, given by G = 6.673 × 10−11 N·m2/kg2.

Answer 2

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.
