Solution
Variation of acceleration due to garvity, g with distance $'d'$ from center of the earth
$If\,\,\,\,\,d < R,g = \frac{{Gm}}{{{R^2}}}.d\,\,\,\,i.e.,g \propto d\left( {straight\,line} \right)$
$If\,\,\,\,\,d = R,{g_s} = \frac{{Gm}}{{{R^2}}}$
$If\,\,\,\,d > R,g = \frac{{Gm}}{{{d^2}}}\,\,\,\,\,\,i.e.,g \propto \frac{1}{{{d^2}}}$
