Question

Santa is riding the elevator and is standing on a scale. his mass is 135 kg. what does the scale read before the elevator starts moving?

Answer 1

135 * 9.81 Newtons
or more likely if the scale is calibrated for use here on earth it would read 135 kg

Answer 2

If Santa were in the elevator at the North Pole - where the earth's radius is less than at the equator - he is closer to the center of the earth and would therefore weigh more.
