The earth can be approximated by a sphere of radius 6370 km. If a person stood on a scale on the North Pole and observed the scale reading
to be mg where the person’s mass was m and the acceleration due to
gravity is g, what would the scale reading be if this same person stood on
the scale on the equator?
