1. The problem statement, all variables and given/known data The rotation of the Earth affects the apparent gravitational acceleration at different latitudes. At a location on the Equator, a man’s weight is registered as 709.7 N on a set of very accurate scales. Assuming a perfectly spherical Earth, determine what the same set of scales would register for the same man’s weight at the North Pole 2. Relevant equations Not sure I have used f=ma and w=mg but dont think I need these as the Earth is perfectly spherical So it might be a=v^2/r 3. The attempt at a solution As far as I can figure if Earth is perfectly spherical then there will be no change in weight due to the force of gravity. But maybe because of the rotation and Centrifugal force this might have a slight effect.
