A) \[\frac{{{\omega }_{0}}}{4}\]
B) \[\frac{{{\omega }_{0}}}{2}\]
C) \[{{\omega }_{0}}\]
D) \[2{{\omega }_{0}}\]
Correct Answer: B
Solution :
\[{{\overrightarrow{L}}_{i}}={{\overrightarrow{L}}_{f}}\] \[(2m{{R}^{2}}){{\omega }_{0}}=(2m{{R}^{2}}+2m{{R}^{2}})w'\]\[w'=\frac{{{\omega }_{0}}}{2}\]You need to login to perform this action.
