A. Mons pubis: A fatty cushion of cells covered by skin and pubic hair. A-II
B. Clitoris: A small, sensitive, erectile organ located above the urethral opening. It is homologous to the penis in males. B-III
C. Hymen: A thin membrane that partially covers the vaginal opening. C-IV
D. Labia majora: Fleshy folds of tissue that extend down from the mons pubis and surround the labia minora and vaginal opening. D-I
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 :
