Question

derive the expression for the variation of acceleration due to gravity g with height and depth from the earth surface​

Answer 1

Answer:

We get, ⇒g=GM(R−d)R3. Therefore the expression of acceleration due to gravity of a body at a depth d from the surface of earth is GM(R−d)R3. Here, we can understand that the acceleration of a body due to gravity inside earth decreases as we go from the surface to the centre of earth. At centre g=0.
