A) \[\frac{1}{4}\frac{M{{L}^{2}}}{{{\pi }^{2}}}\]
B) \[\frac{2M{{L}^{2}}}{3{{\pi }^{2}}}\]
C) \[\frac{M{{L}^{2}}}{2}\]
D) \[\frac{M{{L}^{2}}}{2}\]
Correct Answer: A
Solution :
Here, \[L=\pi R\]or\[R=\frac{L}{\pi }\] \[\therefore \]Moment of inertia about XY \[=\frac{1}{2}\left( \frac{1}{2}M{{R}^{2}} \right)\] \[=\frac{1}{4}\frac{M{{L}^{2}}}{{{\pi }^{2}}}\]You need to login to perform this action.
