Value of effective g increases as we move from equator to north pole because on equator its value is less due to earth's rotational motion and consequent centrifugal force.
Moreover, the equator of the earth is at a larger distance from the centre of the earth as compared to the poles. This is another reason why g is greater on the pole than the equator.
