A) \[\frac{2uM}{m}\]
B) \[\frac{2um}{M}\]
C) \[\frac{2u}{1+\frac{m}{M}}\]
D) \[\frac{2u}{1+\frac{M}{m}}\]
Correct Answer: C
Solution :
\[{{v}_{2}}=\left( \frac{{{m}_{2}}-{{m}_{1}}}{{{m}_{1}}+{{m}_{2}}} \right)\ {{u}_{2}}+\frac{2{{m}_{1}}{{u}_{1}}}{{{m}_{1}}+{{m}_{2}}}\]\[=\frac{2Mu}{M+m}=\frac{2u}{1+\frac{m}{M}}\]You need to login to perform this action.
