Question

How does the acceleration due to gravity, vary with the height from the earth
surface? Obtain a mathematical formula for the acceleration due to gravity on
the surface of the earth.​

Answer 1

Answer: here

Explanation: For an object placed at a height h, the acceleration due to gravity is less as compared to that placed on the surface. As depth increases, the value of acceleration due to gravity (g) falls. The value of g is more at equator and less at poles.

Formula: g = GM/r2

Values of g in SI: 9.806 ms-2

Values of g in CGS: 980 cm s-2
