Question

Drive an expression for acceleration due to gravity​

Answer 1

heya buddy....... ✌

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.

• Formula: g = GM/r2
• Values of g in SI: 9.806 ms-2
• Dimensional Formula: M0L1T-2

HOPE IT HELPS YOU........✨✨❤✨✨

Answer 2

Explanation:

Hi dear ❤️

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.
