In case of binary star system angular velocity and hence the time period of both the stars are equal.

Q. A double star system consists of two stars A and B which have time periods $T_{A}$ and $T_{B}$ . Radius $R_{A}$ and $R_{B}$ and mass $M_{A}$ and $M_{B}$ . Choose the correct option

if $T_{A} > T_{B}$ then $R_{A} > R_{B}$

if $T_{A} > T_{B}$ then $M_{A} > M_{B}$

$(\frac{T _{A}}{T _{B}})^{2} = (\frac{R _{A}}{R _{B}})^{3}$

$T_{A} = T_{B}$

Q. A double star system consists of two stars A and B which have time periods TA​ and TB​ . Radius RA​ and RB​ and mass MA​ and MB​ . Choose the correct option

if TA​>TB​ then RA​>RB​

if TA​>TB​ then MA​>MB​

(TB​TA​​)2=(RB​RA​​)3

TA​=TB​
