A) \[\frac{4}{7}\frac{V}{l}\]
B) \[\frac{3}{7}\frac{V}{l}\]
C) \[\frac{3}{7\sqrt{2}}\frac{V}{l}\]
D) \[\frac{3\sqrt{2}}{7}\frac{V}{l}\]
Correct Answer: D
Solution :
[d] About point P, angular momentum (L) of the System \[{{L}_{\operatorname{initial}}}=\frac{mv}{\sqrt{2}}\times \frac{1}{2}\] \[{{L}_{final}}=\left[ \frac{(4m){{l}^{2}}}{12}+\frac{m{{l}^{2}}}{4} \right]\omega \] As \[{{L}_{initial}}={{L}_{final}}\] \[\omega =\frac{3\sqrt{2}v}{7l}\]You need to login to perform this action.
