If the mass of the Earth becomes four times large, the value of 'g' will:
Correct answer: B. Becomes four times larger
- A. Remain unchanged
- B. Becomes four times larger
- C. Be doubled
- D. Become sixteen times larger
Explanation
Gravitational acceleration= GM/R2 As the mass increases four times so g'= 4gHence the correct option is B.

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.
