## Homework Statement

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

## Homework Equations

Fg=Gm1m2/r^2

Fg=ma

Fc=Mv^2/r?

## 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!
