Match List-I with List-II and select the correct option:
The bond angles \( b_1, b_2, b_3 \) in the above structure are respectively in \( ^\circ \):
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 :
