A circular disc has a mass of \(1 kg\) and radius \(40 cm\). It is rotating about an axis passing through its centre and perpendicular to its plane with speed of \(10 rev / s\). The work done in joules in stopping it would be \(\left(\pi^2 \approx 10\right)\) : 📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
