Question

Q.2 A body weighs more at poles than at equator of earth why?​

Answer 1

Answer:

The body experiences a centrifugal force away from the earth due to rotation of the Earth because of which the weight of the body decreases. The centrifugal force is maximum at the equator and minimum at the poles. Therefore, the body weighs maximum at poles and minimum at the equator.

Answer 2

Answer:

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 is less than at 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.

Hence, the weight of a body at the poles will be greater than at the equator.
