The acceleration of a body due to the attraction of the earth (radius $R$) at a distance $2 \,R$ from the surface of the earth is ($g =$ acceleration due to gravity at the surface of the earth)
The acceleration of a body due to the attraction of the earth (radius $R$) at a distance $2 \,R$ from the surface of the earth is ($g =$ acceleration due to gravity at the surface of the earth)
$\frac{g}{9}$
$\frac{g}{3}$
$\frac{g}{4}$
$g$
The acceleration of a body due to the attraction of the earth (radius $R$) at a distance $2 \,R$ from the surface of the earth is ($g =$ acceleration due to gravity at the surface of the earth)
$g' = g\,{\left( {\frac{R}{{R + h}}} \right)^2} = g\,{\left( {\frac{R}{{R + 2R}}} \right)^2} = \frac{g}{9}$
