The weight of the object is less at the equator than at the poles.

Description : The weight of the object is less at the equator than at the poles.

Last Answer : Ans: The weight of an object is the product of mass and force of gravity. The equatorial diameter is more than the polar diameter. Thus, the force of gravity is more at the poles and the weight is more there.

The weight of the object is less at the equator than at the poles.

Description : The weight of the object is less at the equator than at the poles.

Last Answer : Ans: At equator, the distance from the earth's center is greater than any other point of the earth's surface. Since, weight is defined as the force with which a body is attracted towards the earth's ... the force applied. Hence, the object's weight is lightest at the earth's equator, than at poles.
