Question

How much difference is there between your apparent when standing on flat ground at the equator versus at the south pole? Versus at 60 degree latitude? Assume Earth's radius is 6380 km. What period of rotation for Earth would make you feel weightless at the equator?

Answer 1

Here the basic concept is that as earth is a rotating system anybody kept on earth will experience a centrifugal force which will make the weight appear to be less on equator than on the poles. This difference is dependent upon the lattitude and the Angular velocity of earth if mass and g at South pole is given one can easily find out the values  

solution : The difference in to rolation of Apparent weigne is due Earth on its axis U TV RP marre maple pin Angular velocity of Earth-w At P, (eguator) weight = m (gequator). weight = mg pole - mw Real due to rotation At P2 (south Pole) weight = mgoole Difference = marree/ At Rooz Resin 30° B mopole (60 lattitude) motrok, mwarcosso mgpole - mwaRex t = mg Pole- mad more - m3 Weight = 4 ne
