Question

(iii)Calculate the expression of acceleration due to gravity (g).​

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.

Answer 2

Answer:

Its value near the surface of the earth is 9.8 ms-2. Therefore, the acceleration due to gravity (g) is given by = GM/r2.
