How much more or less does a 53 kg person appear to weigh on the North Pole than they do at the equator. Indicate a positive weight difference with a positive number and a negative weight difference with a negative number. Assume the earth is a perfect sphere. Use the "Useful Planetary Data" in your notes. Hint: Apparent weight is the normal force exerted on the person by the earth (or on the earth by the person). Think of situations where this normal force would not be equal to weight.
