PLEASE ANSWER URGENTLY: Discuss the variation of "g" due to altitude

1.	PLEASE ANSWER URGENTLY: Discuss the variation of "g" due to altitude from the surface of earth. Also find the acceleration due to gravity at a height equal to the radius of earth from the surface of earth.
Answer» r earth to be a sphere of mass M, radius R with centre at O. Let g be the VALUE of acceleration due to gravity at a POINT A on the surface of earth. .....(1)If g' is the acceleration due to gravity at a point B, at a height h above the surface of earth, then the force on the body at B is due to earth whose mass M is concentrated at the centre O of earth. .....(2)Dividing EQ. (2) by Eq. (1), we get.....(3)If h<
