Question

The value of g is maximum

• A. at the poles
• B. at equator of earth
• C. in a mine
• D. at a high hill

Answer 1

The correct option is A

at the poles

To find: The place where value of $g$ is maximum.

Explanation:

1. The distance from the poles to the centre of the earth is lesser than the distance from the equator to the centre of the earth.
2. We have, $g=GM/r^2$.Acceleration due to gravity $g$is inversely proportional to $r$
3. Therefore, the acceleration due to gravity is greater at the poles than at the equator.

Hence, the correct option is (a).
