A satellite moves around the earth in a circular orbit of radius $R$ making one revolution per day. A second satellite moving in a circular orbit moves around the earth once in $8$ days. The radius of the orbit of the second satellite is

Options:

Answer:

Solution:

Given that, $T_{1} = 1$ day and $T_{2} =$ 8 days
∴ $\frac{T_{2}}{T_{1}} = {(\frac{r_{2}}{r_{1}})}^{3 / 2}$ $\Rightarrow$ $\frac{r_{2}}{r_{1}} = {(\frac{T_{2}}{T_{1}})}^{2 / 3} = {(\frac{8}{1})}^{2 / 3} = 4$ $\Rightarrow$ $r_{2} = 4 r_{1} = 4 R$
