A) \[\upsilon \]
B) \[\frac{\upsilon }{2}\]
C) \[\frac{\upsilon }{\sqrt{2}}\]
D) \[\frac{\upsilon }{\sqrt{2}}\]
Correct Answer: C
Solution :
Applying principle of conservation of linear momentum. \[(2m)\upsilon =\sqrt{{{(m\upsilon )}^{2}}+{{(m\upsilon )}^{2}}}=m\upsilon \sqrt{2}\] \[\upsilon =\frac{\upsilon \sqrt{2}}{2}=\frac{\upsilon }{\sqrt{2}}\] Hence, the correction option is [c].You need to login to perform this action.
