The southern Hemisphere of Earth is "up side down", but the people living there do not fall off the Earth because:
Correct answer: A. Earth attracts every body nearly towards its centre
- A. Earth attracts every body nearly towards its centre
- B. Their weight is zero
- C. Their weight is infinite
- D. The value of g is zero in the Southern Hemisphere
Explanation
This option is correct. The force of gravity acts toward the center of the Earth. Regardless of where you are on the Earth's surface, gravity is pulling you toward its center. This gravitational force is what keeps people, and everything else, grounded on the Earth.

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.
