A) \[5\,rad/s\]
B) \[\sqrt{30}\,red/s\]
C) \[\sqrt{60}\,red/s\]
D) \[10\,red/s\]
Correct Answer: A
Solution :
[a] \[T-mg=m{{\omega }^{2}}r\] \[30-0.5\times 10=0.5{{\omega }^{2}}\times 2\] \[30-5={{\omega }^{2}}\] \[25={{\omega }^{2}}\] \[\omega =5rad/\sec \]You need to login to perform this action.
