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 gravitational force 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.
I understood the first point, but not the second one. Shouldn't the gravitational force at the equator be greater as there is more mass pulling the body perpendicular to the tangent (since there is more mass aligned along this axis)?
