If the mass of the earth becomes double, then value of "G" _:
Correct answer: B. Remains same
- A. Also doubles
- B. Remains same
- C. Four times
- D. Two times
Explanation
The value of the gravitational constant (G) is not affected by changes in the mass of the Earth or any other celestial body. The gravitational constant is a fundamental constant of nature and is considered to be universal and constant throughout the universe. If the mass of the Earth becomes double, it will affect the force of gravity between two objects on Earth, but (G) remains constant. In other words, (G) is a fundamental constant that doesn't change based on the masses involved in the gravitational interaction.

About Gravitation
Newton’s law of universal gravitation relates the force between masses to their masses and separation, while gravitational field strength explains weight and orbital motion. The topic covers satellite velocity and period, escape ideas, weightlessness in free fall, and artificial gravity, which differs from ordinary gravitational attraction.
