The acceleration due to gravity g is proportional to r till thesurface of Earth and is inversely proportional to r2 outside the surface of Earth.
That is, g ∝ r ; till surface of Earth
g∝

r2

; outside the surface of Earth
Therefore, the graph shows linear behaviour till the surface of Earth, that is, till r and beyond R it shows

r2

decay thus the variation of g on the Earth is represented as
