Question

write down change in gravitation acceleration for 10km.

Answer 1

Solution

An body is at height h then at this point gravitational acceleration g is given by

$g'=\frac{g}{(1+\frac{h}{R})^2}$

Where

g is gravitational acceleration at earth 's surface.

R is radius of earth.

Often at height 0-10 Km gravitational acceleration is taken constant acceleration $9.81 m/s^2.$
