Physics - Gravitation Question with Solution | TestHub

The acceleration due to gravity on moon is ${\left(\frac{1}{6}\right)}^{\text{th }}$ times the acceleration due to gravity on earth. If the ratio of the density of earth ' ${\varrho }_e$ ' to the density of moon ${\varrho }_m$ ' is $\frac{5}{3}$, then the radius of moon ' $\mathrm{Rm}$ ' in terms of the radius of earth 'Re' is
