A) \[\frac{r\omega {{\,}_{0}}}{4}\]
B) \[\frac{r\omega {{\,}_{0}}}{3}\]
C) \[\frac{r\omega {{\,}_{0}}}{2}\]
D) \[r\omega {{\,}_{0}}\]
Correct Answer: C
Solution :
From conservation of angular momentum about bottom most point. \[m{{r}^{2}}{{\omega }_{0}}\,=mvr\,+m{{r}^{2}}\,\times \frac{v}{r}\,\Rightarrow \,v=\frac{{{\omega }_{0}}r}{2}\]You need to login to perform this action.
