The weight of a person or object is _______ at the poles than at the equator.
A. slightly less
B. the same
C. slightly greater
D. much less
C. slightly greater. [ First, gravitational pull is stronger the closer you are to the center of the gravitational object and the earth is slightly flattened with the poles closer to the center, so the weight will be greater at the poles.
Second, because of centrifugal force due to the spinning of the earth of its axis, objects at the equator tend to be pulled up away from the earth, and
would therefore exert less force on a balance or scale. That doesn't happen at the poles, so the apparent weight at the equator would again be less than at the poles.
