The bulging of the earth at the equator and flattening at the poles is due to

Earth is flattened at poles and bulging at the equator . This is due to

The earth is not a perfect square. Why does it bulge at the equator and flattens at the poles.

Assuming that the whole variation of the weight of a body with its position on the surface of the earth is due to its rotation , find the difference in the weight of 5 kg as measured at the equator and at the poles . Radius of the earth = 6.4 xx 10^(6) m.

If earth were to rotate on its own axis such that the weight of a person at the equator becomes half the weight at the poles, then its time period of rotation is (g = acceleration due to gravity near the poles and R is the radius of earth) (Ignore equatorial bulge)

If earth were to rotate on its own axis such that the weight of a person at the equator becomes half the weight at the poles, then its time period of rotation is (g = acceleration due to gravity near the poles and R is the radius of earth) (Ignore equatorial bulge)

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
