Question

Does the concentration of the earth's mass near its center change the variation of g with height compared with a homogeneous sphere ? How?

Answer 1

Hi,

Here is your answer,

Any change in the distribution of the earth's mass will not affect the variation of acceleration due to gravity with height. This is because for a point outside the earth, the whole mass of the earth is effective and the earth behaves as a homogeneous sphere.
