A double star system consists of two stars

A

and

B

which have time period

T_A

and

T_B

. Radius

R_A

and

R_B

and mass

M_A

and

M_B

. Choose the correct option.

Options

AIf $T_A>T_B$ , then $R_A>R_B$
BIf $T_A>T_B$ , then $M_A>M_B$
C $\left(\frac{T_A}{T_B}\right)^2=\left(\frac{R_A}{R_B}\right)^3$
D $T_A=T_B$

Correct answer

D. $T_A=T_B$

Step-by-step solution

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