Question

A 74 kg man weighs himself at the north pole and at the equator.By how much?

Answer 1

<<In combination, the equatorial bulge and the effects of the surface centrifugal force due to rotation mean that sea-level effective gravity increases from about 9.780 m/s2 at the Equator to about 9.832 m/s2 at the poles, so an object will weigh about 0.5% more at the poles than at the Equator.>> from wiki
