The centripetal acceleration of a person standing at the equator is about 0.03 m s–2.
(Radius of the Earth = 6.4 × 106 m.)
The size of the force R provides a measure of the apparent strength of the gravitational field. Show that the apparent field strength g at the equator differs from that at the poles by about 0.3%.
The answer is:
(0.034 ÷ 9.81) × 100% = 0.35%
I don't understand this. How do we know that the acc at the pole is 9.81, and that 0.034 is the difference in the 2 accerelations?
