A) zero
B) \[\sqrt{\frac{6g}{5l}}\]
C) \[\sqrt{\frac{3g}{5l}}\]
D) none
Correct Answer: B
Solution :
Moment of inertia of system of rods about P: \[l=\left( \frac{m{{l}^{2}}}{3} \right)\,\,+\,\,\left[ \frac{m{{l}^{2}}}{l2}+\frac{m5{{l}^{2}}}{4} \right]\,\,=\,\,\frac{5}{3}\,m{{l}^{2}}\]You need to login to perform this action.
