1. The problem statement, all variables and given/known data Suppose the earth is a perfect sphere with R=6370 km. if a person weighs exactly 600.0 N at the north pole how much will the person weigh at the equator? (hint: the upward push of the scale on the person is what the scale will read and is what we are calling the weight in this case) ans: 597.9 N 2. Relevant equations Fg=Gm1m2/r^2 Fg=ma Fc=Mv^2/r? 3. The attempt at a solution I have no real clue on how to solve such a question, i plugged in for Fg but the answer i seem to get is higher than that of 597.9 N. Need help for a solution please!!!!!
