Question

Earth is not a perfect sphere,its radius is not the same . a) Where will the value of 'g' be the maximum on the Earth's surface ? b) Where will be the minimum ? c) What will be the value of 'g' at the centre of the Earth ? d) What is the average value of 'g'​

Answer 1

Answer:

• The earth is not a perfect sphere. As the radius of the earth increases from the poles to the equator, the value of g becomes greater at the poles than at the equator.

Answer 2

Explanation:

By changing the radius, moment of inertia will change. Hence, angular speed ω will change.But ω has no effect on the value of g on pole.

The earth is not a perfect sphere. As the radius of the earth increases from the poles to the equator, the value of g becomes greater at the poles than at the equator
