Question
What is the variation in acceleration due to gravity with altitude?
✓

Answer

Variation in acceleration due to gravity due to altitude is given by, $g_h= g \left(\frac{R}{R+h}\right)^2$ where,
$g_h=$ acceleration due to gravity of an object placed at $h$ altitude
$g=$ acceleration due to gravity on surface of the Earth
$R=$ radius of the Earth
$h=$ attitude height of the object from the surface of the Earth.
Hence, acceleration due to gravity decreases with increase in altitude.
