2007 F = ma Exam — Question 23

23. If a planet of radius R spins with an angular velocity ω about an axis through the North Pole, what is the ratio of the normal force experienced by a person at the equator to that experienced by a person at the North Pole? Assume a constant gravitational field g and that both people are stationary relative to the planet and are at sea level.
