At the equator, the centrifugal force due to the Earth's rotation cancels out some of the gravitational force, resulting in a lower 'g' value. There is no centrifugal force at the poles and the value of 'g' is higher. Hence the value of 'g' is lower at the equator than at the poles.Also, Equatorial radius is about 21 km longer than the polar radius.
