A) \[\frac{m{{l}^{2}}}{24}\]
B) \[\frac{m{{l}^{2}}}{12}\]
C) \[\frac{m{{l}^{2}}}{6}\]
D) \[\frac{m{{l}^{2}}}{18}\]
Correct Answer: B
Solution :
As, \[{{l}_{PR}}={{l}_{QS}}=\frac{m{{l}^{2}}}{12}\] (for the figure) Hence, only for triangular part, moment of inertia \[I=\frac{m{{l}^{2}}}{12},\] where m is the mass of the triangular sheet.You need to login to perform this action.
