A) \[\sqrt{3}/4\]
B) \[4/\sqrt{3}\]
C) \[1/\sqrt{3}\]
D) \[\sqrt{3}\]
Correct Answer: A
Solution :
Apply the law of conservation of linear momentum along a direction perpendicular to the direction of motion (i.e. along y-axis), we get \[0+0=4{{v}_{1}}\,\sin 30{}^\circ -{{v}_{2}}\sin 60{}^\circ \] \[4{{v}_{1}}\sin 30{}^\circ ={{v}_{2}}\sin 60{}^\circ \] \[\frac{{{v}_{1}}}{{{v}_{2}}}=\frac{\sin 60{}^\circ }{4\sin 30{}^\circ }=\frac{\sqrt{3}}{4}\]You need to login to perform this action.
