Newton’s law of gravitation is valid on

CONCEPT:

Newton's law of Gravitation:

• Newton's law of gravitation states that everybody in this universe attracts every other body with a force, which is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
• The direction of the force is along the line joining the particles.
• The magnitude of the gravitational force F is

\(F = G\frac{{{M_1}{M_2}}}{{{R^2}}}\)

Where G = universal gravitational constant, M1 = mass of 1st body, M2 = mass of 2nd body, and R = distance between the two bodies.

EXPLANATION:

• The gravitational constant is a scalar quantity. Its value is the same throughout the universe and is independent of the nature and size of the bodies as well as the nature of the medium between the bodies.
• Thus, Newton's law of Gravitation holds good for two objects

1. of any shape, size, and mass. Thus, option 2 is correct.
2.  at all places
3. at all times throughout the universe.

So, the correct option is 'all bodies'
