Why is the pull of gravity more at the poles than at than at the equator.

Why the gravitational force is greater near the poles and less at equator?

Gravitational force of Earth is minimum at equator because the centrifugal force at the equator is maximum.

Centrifugal force is an outward force exerted on a body revolving in a circular path, to mantain its state of motion.

Explanation:

Here Earth revolves around its axis and the same forces act on it to enable its revolution.

Gravitational force at the equator is less because Centrifugal force, which is also acting at the equator cancels out the Gravitational force to an extent. Whereas at poles, there is no such effect of centrifugal force because earth is sphere (bulged at center; flat at poles )and hence gravitational force is maximum at poles.

The other reason is distance from any place on equator to centre of earth is more than at poles. Because Earth is bulged at centre and flat at poles. Since Gravitational force is given by

F= GMm/ r^2 ; r is the distance between two bodies.
