Question

Why does a body weigh more at the poles than at the equator?

Answer 1

A body weighs more at the poles than at the equator because the earth is not a perfect sphere, but it is flattened at the poles. The distance between the equator and the center
of the earth and the poles is less; therefore the force of gravitation is more at the poles than at the equator, and so it weighs more at the poles than equator.
