A) \[\frac{u}{2a}\]
B) \[\frac{4u}{3a}\]
C) \[\frac{u}{3a}\]
D) \[\frac{3u}{4a}\]
Correct Answer: D
Solution :
Conserving angular momentum about A, we get \[mua=I\omega \] \[\therefore \]\[mua=\frac{m{{(2a)}^{2}}}{3}\omega \Rightarrow \,\omega =\frac{3u}{4a}\] Hence, the correction option is [a].You need to login to perform this action.
