If the value of G is doubled, the value of g:
Correct answer: A. Is also doubled
- A. Is also doubled
- B. Remains the same
- C. Becomes one half
- D. Become a quarter of the original value
Explanation
Correct Answer: A If the value of universal constant G is doubled, the value of g is also doubled. according to the given formula: g=GM/R2 G and g are directy proportional to each other if M and R are kept constant.

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.
