A) \[\frac{3}{2}m{{l}^{2}}\]
B) \[\frac{3}{4}m{{l}^{2}}\]
C) \[2\,m{{l}^{2}}\]
D) \[\frac{5}{4}\,m{{l}^{2}}\]
Correct Answer: D
Solution :
Moment of inertia of the system \[l={{l}_{1}}+{{l}_{2}}+{{l}_{3}}=0+m{{\left( \frac{l}{2} \right)}^{2}}+m{{l}^{2}}\] \[=\frac{m{{l}^{2}}}{4}+m{{l}^{2}}=\frac{5}{4}m{{l}^{2}}\]You need to login to perform this action.
