Question

Why the value of ‘g’ decreases when we move from poles to equator?

Answer 1

Answer:

We know that the shape of the earth is not a perfect sphere. It is flattened at the poles and bulged at the equator. So the polar radius is smaller than the equitorial radius. ... Thus the value of g on earth is maximum at poles and decreases as we go from poles to the equator and is minimum at the equator.

Answer 2

Answer:

because if we know that when we go the inside the earth from the surface or we can say that towards the centre of earth or towards the universe means opposite from the same surface of the Earth then the gravity decreases.

so as we know that the centre of earth from the poles is maximum distance to the equator.

so when we go from the pole to the equator than the distance between the centre of the earth from surface of the earth decreases so the value of g decreases.
