A) \[\frac{v}{\sqrt{2}}\]
B) \[\frac{v}{2}\]
C) \[v\]
D) \[v\sqrt{2}\]
Correct Answer: D
Solution :
From law of conservation of momentum, \[mv-mv\cos \theta =0\] ... (i) \[mv-mv\sin \theta =0\] ... (ii) From Eqs. (i) and (ii), we get \[\theta ={{45}^{o}}\] \[v\frac{v}{\cos \theta }=v\sqrt{2}\]You need to login to perform this action.
