A. Joint between humerus and pectoral girdle: This is the shoulder joint, which is a ball-and-socket joint, allowing for a wide range of motion. A-II
B. Knee joint: The knee joint is a hinge joint, allowing for flexion and extension. B-III
C. Joint between atlas and axis: This joint between the first two cervical vertebrae (atlas and axis) is a pivot joint, allowing for rotation of the head. C-IV

A bob of heavy mass \(m\) is suspended by a light string of length \(l\). The bob is given a horizontal velocity \(v_0\) as shown in figure. If the string gets slack at some point P making an angle \( \theta \) from the horizontal, the ratio of the speed \(v\) of the bob at point P to its initial speed \(v_0\) is :
