A ballot dancer is rotating at angular velocity \(\omega\) on smooth horizontal floor. The ballot dancer folds his body close to his axis of rotation by which his radius of gyration decreases by \(1 / 4^{\text {th }}\) of his initial radius of gyration, his final angular velocity is 📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
