The period of a satellite in a circular orbit of radius $R$ is $T$, the period of another satellite in a circular orbit of radius $4R$ is
The period of a satellite in a circular orbit of radius $R$ is $T$, the period of another satellite in a circular orbit of radius $4R$ is
$4T$
$\frac{T}{4}$
$8T$
$\frac{T}{8}$
The period of a satellite in a circular orbit of radius $R$ is $T$, the period of another satellite in a circular orbit of radius $4R$ is
$\frac{{{T_1}}}{{{T_2}}} = {\left( {\frac{{{R_1}}}{{{R_2}}}} \right)^{3/2}}$
$= {\left( {\frac{R}{{4R}}} \right)^{3/2}}$
$\Rightarrow \,{T_2} = 8{T_1}$
