There is a body lying on the surface of the Earth and suppose the Earth suddenly loses its power of attraction then:
Correct answer: B. The weight of the body will reduce to zero
- A. The mass of the body will reduce to zero
- B. The weight of the body will reduce to zero
- C. Both will reduce to zero
- D. It becomes infinity
Explanation
Statement B is correct. Weight is the force with which gravity pulls an object toward the center of the Earth (or any celestial body). If the Earth were to lose its gravitational attraction, the object would no longer experience a gravitational force, and its weight would become zero.

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.
