Question

the weight of object is more in the poles than the equator of the earth why

Answer 1

Explanation:

Thus more massive objects, of course, weigh more in the same location; the farther an object is from the Earth, the smaller is its weight. The weight of an object at the Earth's South Pole is slightly more than its weight at the Equator because the polar radius of the Earth is slightly less than the equatorial radius.

Answer 2

Explanation:

weight of a body is the pull of the force by which it attracted towards the centre of earth.

Since, the equator is more far from centre of earth as compared to that of distance of poles from center of earth. Hence, the more the distance will be the less will be the weight measured.

This is the main reason reason why the weight of an object is maximum at poles as compared to that on equator.
