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

Answer Posted / sanju

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