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

View answer and explanation

Correct option: B

{T_A} = {T_B}

Option B is correct because in a binary star system, both stars orbit their common center of mass with the same period.

around the earth so as to rotate opposite to each other. If they collide inelastically and stick together as wreckage, the total energy of the system just after collision is Statement-1: There is almost no effect of rotation of earth at poles.
Statement-2: Because rotation of earth is about polar axis.
