Acceleration due to gravity $'g'$ for a body of mass $'m'$ on earth's surface is proportional to (Radius of earth$=R$, mass of earth$=M$)
Acceleration due to gravity $'g'$ for a body of mass $'m'$ on earth's surface is proportional to (Radius of earth$=R$, mass of earth$=M$)
$GM/{R^2}$
${m^0}$
$mM$
$1/{R^{3/2}}$
Acceleration due to gravity $'g'$ for a body of mass $'m'$ on earth's surface is proportional to (Radius of earth$=R$, mass of earth$=M$)
$F=\frac{G M M}{R^2}=m g \Rightarrow g=\frac{G M}{R^2}$
$g \propto \frac{G M}{R^2}$
