The value of 'g' on poles is:
Correct answer: A. Maximum
- A. Maximum
- B. Minimum
- C. Zero
- D. None of the above
Explanation
This is the following solution: The earth's radius at poles is the least, so acceleration due to gravity will be highest at poles because g is inversely proportional to the square of the radius. Gravitational force is always inversely proportional to the distance between the earth's center and the object under study.

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.
