Key Idea The relation of gravitational acceleration at an altitude above the earth's surface is given as
where, is the acceleration due to gravity at earth's surface and is the radius of the earth.
Given that at some height , acceleration due to gravity,
The ratio of acceleration due to gravity at earth's surface and at some altitude is
[From Eq. (i)]
or
)
Thus, at mabove the earth's surface, the acceleration due to gravity decreases to .
