An object of mass \(m\) is attached to light string which passes through a hollow tube. The object is set into rotation in a horizontal circle of radius \(r_1\). If the string is pulled, shortening the radius to \(r_2\), the ratio of new kinetic energy to the original kinetic energy is 📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
