Question 209 of 210

Two point masses of mass $m_1=f M$ and $m_2=(1-f) M(f \lt 1)$ are in outer space (far from gravitational influence of other objects) at a distance $R$ from each other. They move in circular orbits about their centre of mass with angular velocities $\omega_1$ for $m_1$ and $\omega_2$ for $m_2$ . In that case

Show answer and solution

Answer: (B) $\omega_1=\omega_2$ and independent of $f$

Angular velocity is the angular displacement per unit time i.e.,

\omega=\frac{\Delta \theta}{\Delta t}

Here

w_1=w_2

and independent of

f
