Variation of 'g' with altitude


Let a body of mass m be placed on the surface of the Earth, whose mass is M and radius is R.
From equation (4)
Let the body be now placed at a height h above the Earth's surface. Let the acceleration due to gravity at that position be g|.
For comparison, the ratio between g| and g is taken
