The earth is not a perfect sphere because its equatorial axis is longer than the polar axis. where on the earth's surface would an object have its greatest weight?
half way between the equator and the north pole
near the equator
half way between the equator and the south pole
at either pole
at the equator
설명
The acceleration due to gravity is maximum at the poles and minimum at the equator, therefore the weight of the object will be maximum at the poles.
