Step-by-step solution

The acceleration due to gravity (g\mathrm{g}) is proportional to (r\mathrm{r}) till thesurface of Earth and is inversely proportional to r2r^{2} outside the
surface of Earth.
That is, (g \propto r); till surface of Earth
(g \propto 1r2\frac{1}{r^{2}}); outside the surface of Earth
Therefore, the graph shows linear behaviour till the surface of Earth, that is, till rr and beyond RR it shows (1r2\frac{1}{r^{2}}) decay thus
the variation of gg on the Earth is represented as
Variation of acceleration due to gravity (g) with distance x from the centre of the earth is best represented by ( (R
