Question

the value of g become greater at the poles than that at the equator give reason
​

Answer 1

Answer:

As,The earth is not a perfect sphere,The gravity keeps on changing as we move from one place to another. But it is maximum at the place where it is nearer to the center. so,Earth's gravity is the maximum at the poles because the Earth is kind of an ellipse (not a perfect sphere.) And the equator is further away from the center of mass of the Earth than at the poles.

so,As we go from equator to poles, the value of g Increases.
