A) \[\frac{1}{25}\]
B) \[\frac{1}{5}\]
C) 5
D) 25
Correct Answer: C
Solution :
As discussed in above problem\[=\frac{{{m}_{1}}-{{m}_{2}}}{{{m}_{1}}+{{m}_{2}}}=\frac{{{v}_{1}}}{{{v}_{2}}}\] \[=\frac{1}{1.5}=\frac{2}{3}\] or, \[\frac{{{m}_{1}}-{{m}_{2}}}{{{m}_{1}}+{{m}_{2}}}=\frac{3}{2}\] Applying componendo and dividendo, we have \[\frac{{{m}_{1}}}{{{m}_{2}}}=\frac{3+2}{3-2}=\frac{5}{1}\]You need to login to perform this action.
