A horizontal uniform rod of length \(L\) and mass \(M\) is pivoted at one end and is initially at rest. A small ball of mass \(M\) (same masses) is attached to the other end of the rod. The system is released from rest. What is the angular acceleration of the rod just immediately after the system is released?
