Physics - Gravitation Question with Solution | TestHub

Two satellites 'A' and 'B' are revolving with critical velocities ' ${\mathrm{v}}_{\mathrm{A}}$ ' and ' ${\mathrm{v}}_{\mathrm{B}}$ ' around the earth, in circular orbits of radii ' $\mathrm{R}$ ' and ' $2{\mathrm{R}}^{\prime }$, respectively. The ratio $\frac{{\mathrm{V}}_{\mathrm{A}}^{\prime }}{{\mathrm{V}}_{\mathrm{B}}}$ is
