A) \[3\upsilon \]
B) \[\frac{\upsilon }{2}\]
C) \[\upsilon \text{/3}\]
D) \[2\upsilon \]
Correct Answer: C
Solution :
According to conservation of momentum \[{{m}_{1}}{{\upsilon }_{1}}+{{m}_{2}}{{\upsilon }_{2}}=({{m}_{1}}+{{m}_{2}})\upsilon \] \[m\upsilon +2m\times 0=(m+2m)\upsilon \] So, \[\upsilon =\frac{\upsilon }{3}\]
