Anwser is #1 because t<span>he equator is moving faster than the poles and so extends outward a bit due to centrifugal force. That means a point on the equator is a tiny bit farther from the centre of the Earth than the poles. </span>
<span>The gravitational acceleration at the equator is 9.789 m/s^2m, and 9.832 m/s^2 at the pole.</span>
