A) \[\frac{{{m}_{1}}{{m}_{2}}}{{{m}_{1}}+{{m}_{2}}}{{I}^{2}}\]
B) \[\frac{{{m}_{1}}+{{m}_{2}}}{{{m}_{1}}{{m}_{2}}}{{I}^{2}}\]
C) \[({{m}_{1}}+{{m}_{2}}){{I}^{2}}\]
D) \[\sqrt{{{m}_{1}}{{m}_{2}}}{{I}^{2}}\]
Correct Answer: A
Solution :
\[{{X}_{1}}\frac{{{m}_{2}}I}{{{m}_{1}}+{{m}_{2}}}and\,{{X}_{2}}=\frac{{{m}_{1}}I}{{{m}_{1}}+{{m}_{2}}}\] \[I={{m}_{1}}{{X}_{1}}^{2}+{{m}_{2}}{{X}_{2}}^{2}=\frac{{{m}_{1}}{{m}_{2}}}{{{m}_{1}}+{{m}_{2}}}{{I}^{2}}\]You need to login to perform this action.
