Question

Two satellites $\mathrm{s}_{1}$ and $\mathrm{s}_{2}$ are orbiting around a planet of radius R . $\mathrm{s}_{1}$ is moving close to its surface while $s_{2}$ in an orbit of radius $4 R$. The ratio of their orbital speeds $v_{1} / v_{2}$ is\

Professor PC Thomas Classes · Answer

$\mathrm{v}_{1}=\frac{\mathrm{GM}}{\mathrm{R}}$\ $\mathrm{v}_{2}=\sqrt{\frac{\mathrm{GM}}{4 \mathrm{R}}} \quad \frac{\mathrm{v}_{1}}{\mathrm{v}_{2}}=$
