To maintain a constant separation distance \( r_0 \) between two equal masses, the required angular velocity \( \omega \) must balance gravitational and centripetal forces. The gravitational force is given by \( |F_{g}|=\frac{m^{2}G}{r_{0}^{2}} \), while centripetal acceleration can be expressed as \( a_{c}=\frac{v_{\tan}^{2}}{r_{0}} \). The tangential velocity \( v_{\tan} \) relates to angular velocity through \( v_{\tan}=\omega \,r_{0} \). Setting the origin at the center of gravity allows for uniform circular motion, simplifying the calculation of angular velocity. Understanding these dynamics is crucial for analyzing systems like binary star systems in astrophysics.
