(a) Prove that the rate of change of angular momentum of a system of particles about a reference point is equal to the net torque acting on the system.\n(b) There is a stick half of which is wooden and half is of steel. (i) it is pivoted at the wooden end and a force is applied at the steel end at right angle to its length (ii) it is pivoted at the steel end and the same force is applied at the wooden end. In which case is the angular acceleration more and why ? 📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
