Question
At what height from the surface of the earth the acceleration due to gravity is 1% less than that on the surface of the earth?
Solution
The acceleration due to gravity at the surface of the earth is,
...(1)
Let at height h from the surface of the earth, the acceleration due to gravity be 1% less than that on the surface of the earth.
∴
...(2)
From (1) and (2),
h = 32km, is the height from the surface of the earth.
