Correct Answer - Option 4 : None of the above
The correct answer is option 4) i.e. None of the above
CONCEPT:
-
Law of Universal Gravitation: It states that all objects attract each other with a force that is proportional to the masses of two objects and inversely proportional to the square of the distance that separates their centres.
It is given mathematically as follows:
\(F = \frac{Gm_1m_2}{R^2}\)
Where m1 and m2 are the mass of two objects, G is the gravitational constant and R is the distance between their centres.
- The gravitational constant G establishes a relationship between gravitational force, mass, and distance.
- The value of G is 6.67 × 10-11 N kg-2 m2.
EXPLANATION:
- The law of gravitation is called universal as it is the same for all bodies in the universe irrespective of the medium, temperature, and other physical conditions of the body.
- Hence, the gravitational constant does not depend on any of the parameters listed above.
