Question

why gravitational force at Pole is less than at equator? ​

Answer 1

Explanation:

Many sources state that the Earth's gravity is stronger at the poles than the equator for two reasons: The centrifugal "force" cancels out the gravity minimally, more so at the equator than at the poles. The poles are closer to the center due to the equatorial bulge, and thus have a stronger gravitational field.

Answer 2

Gravitational Force is less than the equator because

The centrifugal "force" cancels out the gravity minimally, more so at the equator than at the poles.

Or

The poles are closer to the center due to the equatorial bulge, and thus have a stronger gravitational field.
