Question

what is the acceleration due to gravity on the earth's surface ? how it varies with height and depth​

Answer 1

Answer:

At the centre of the earth d = R, hence acceleration due to gravity at the centre of the earth is zero. Thus the acceleration due to gravity at a small height 'h' from the surface of the earth is the same as the acceleration due to gravity at the depth 'd = 2h' below the surface of the earth.

Explanation:

Answer 2

Answer:

The acceleration of an object changes with altitude. The change in gravitational acceleration with distance from the centre of Earth follows an inverse-square law. This means that gravitational acceleration is inversely proportional to the square of the distance from the centre of Earth.
