A body is taken to a height of n R from the surface of the earth. The ratio of the acceleration due to gravity on the surface to that at the altitude is

Step-by-step solution

Aceleration due to gravity at a height h above the earth surface g^ =g ( R R+h )² array l g g^ = ( R+h R )² g g^ = ( R+n R R )² g g^ =(1+n)² array
