Question

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

Answer 1

gravitational force near the poles is greater because poles are nearer to the center of earth than the equator and gravitational force is inversely proportional to the square of distance.

Answer 2

because it is inversely proportionaly to radius of earth and radius is less on poles as earth is oval shaped so as the radius is less the force of gravity is maximum on poles.
