A circular disc of mass \(M\) and radius \(R\) is rotating about its axis with angular speed \(\omega_{1}\). If another stationary disc having radius \(\frac{R}{2}\) and same mass \(M\) is dropped co-axially on to the rotating disc. Gradually both discs attain constant angular speed \(\omega_{2}\). The energy lost in the process is \(p \%\) of the initial energy. Value of \(p\) is 📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
