પૃથ્વીની ત્રિજ્યા અને દળમાં 0.5% નો વધારો

$g = \frac{{GM}}{{{R^2}}},{v_e} = \sqrt {\frac{{2GM}}{R}} $ and $U = \frac{{ - GMm}}{R}$

 $g \propto \frac{M}{{{R^2}}}$,

${v_e} \propto \sqrt {\frac{M}{R}} $ and $U \propto \frac{M}{R}$

If both mass and radius are increased by $0.5\%$ then ${v_e}$ and $U$ remains unchanged where as $g$ decrease by $0.5\%$.
