Question

What is the effect of non-sphericity of the earth on the value of g?

Answer 1

Lately it has become possible to sufficiently precise definition of the physical and geometric characteristics of asteroid systems using radar observations (http://echo.jpl.nasa.gov/~lancew

Answer 2

Hey Mate !!

✞All Formulae and equation have been derived by assuming that the earth is a uniform solid sphere. The shape of the earth slightly deviates from the perfect sphere.

✞The Radius in the equatorial plane is about 21Km larger than the radius along the poles.

✞Due to this the force of gravity is more at the poles and less at the equator.

✞The value of g is accordingly larger at the poles and the less at the equator.

✞Note :- Due to rotation of the earth also , the value of g is smaller at the equator and that at the poles.
