Question

Why value of g is greater at pole?

Answer 1

Explanation:

Earth is not a perfect sphere. 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. ... Therefore the acceleration due to gravity is greater at the poles than at the equator.

Answer 2

Answer:

The shape of the earth is not perfectly spherical. It is slightly flattened at the poles and bulged at the equator. As a result, the radius of the earth at the poles is less than that at the equator. ... Hence, the value of acceleration due to gravity (g) is greater at the pole than at the equator.
