Q1

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:

[JEE Main 2021, 20 July (Shift 2)]

a

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

b

\(T_A=T_B\)

c

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

d

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