The weight of an object is more at the poles than at the equator. Is it beneficial to purchase goods at equator and sell them at the pole? Does it matter whether a spring balance is used or an equal beam balance is used?

A body weighs more at poles than at the equator of earth. Why ?

Why the value of acceleration due to gravity is more at the poles than at the equator?

Why is the weight of a body at the poles more than the weight at the equator ? Explain.

The spring balance does not read properly after its long use because

The spring balance does not read properly after its long use because

If weight of an object at pole is 196 N then weight at equator is [ g = 10 m/s^2 , radius of earth = 6400 Km]

Let omega be the angular velocity of the earth's rotation about its axis. Assume that the acceleration due to gravity on the earth's surface has the same value at the equator and the poles. An object weighed by a spring balance gives the same reading at the equator as at a height h above the poles (h lt lt R) . The value of h is

The weight of a body at the poles is greater thasn the weight at the equator. Is it the actual weight or the apparent weight we are talking about? Does your answer depend on whether only the earth's roptation is taken into account or the flattening of the earth at the poles is also taken into account?
