Question

Consider a binary star system of star A and star B with masses $m_A$ and $m_B$ revolving in a circular orbit of radii $r_A$ and $r_B$, respectively. If $T_A$ and $T_B$ are the time period of star A and star B, respectively, then:

Select the correct option:

$\frac{T_A}{T_B}=\left(\frac{r_A}{r_B}\right)^{\frac{3}{2}}$

$T_A=T_B$

$T_A>T_B\left(\right.$ if $\left.m_A>m_B\right)$

$T_A>T_B\left(\right.$ if $\left.r_A>r_B\right)$

✓ Correct! Well done.

✗ Incorrect. Try again or view the solution.

Solution

Tₐ = Tᵦ (since ωₐ = ωᵦ)
