Q. What is the gravitational forceon the sphase of earth?

Answer»

Theearthis not exactly asphere, it bulges at the equator, nor is its density uniform. In addition, its rotation causes the value of g to decrease slightly as one moves from the poles to the equator. However, all of these effects are less than 1% of the nominal value of 9.81 m/s2at theearth'ssurface.
