Answer:
A cording to Newton gravitational law
"g"acceleration=M(mass of each)×G(gravitational constant)÷radius of earth (distance from centre)
If you take ratio you get
g"=g(original gravity of the earth)×R(distance from centre to sure of earth)÷(R+H(height above surface)
This shows that the pattern between gravitational force and distance from Earth's cente goes on decreasing
