A metal sphere of radius \(r\) and specific heat \(S\) is rotated about an axis passing through its centre at a speed of \(\mathrm{f}\) rotations per second. It is suddenly stopped and \(50 \%\) of its energy is used in increasing its temperature. Then the rise in temperature of the sphere is :  📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
