An object is taken from the earth to a planet where the value 'g' is 20 m/s2, if it is compared with value of 'g' earth, which of the following statement is true?
Correct answer: A. Weight at the planet will be greater
- A. Weight at the planet will be greater
- B. Weight at the Earth will be greater
- C. Mass at the planet will be greater
- D. Mass at the planet will be smaller
Explanation
This is more likely to be true. If the value of g on the planet is 20 m/s², and on Earth, it is approximately 9.8 m/s², then the weight on Earth would be greater because W=mg, and the mass (m) remains 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.
