In the arrangements shown in the figure masses of each ball is \( 1 \mathrm{~kg} \) and mass of trolley is \( 4 \mathrm{~kg} \). In the figure, shell of mass \( 1 \mathrm{~kg} \) moving horizontally with velocity \( v=6 \mathrm{~ms}^{-1} \) collides with the ball and get stuck to it then its maximum deflection of the thread (length \( 1.5 \mathrm{~m} \) ) with vertical is
(1) \( 53^{\circ} \)
(2) \( 37^{\circ} \)
(3) \( 30^{\circ} \)
(4) \( 60^{\circ} \)
