A) 10
B) \[\sqrt{10}\]
C) 20
D) 15
Correct Answer: A
Solution :
From the relation, \[T=u{{r}^{2}}{{\omega }^{2}}=\mu {{v}^{2}}\] \[(\because \,v=r\omega )\] \[{{v}^{2}}=\frac{T}{\mu }\] \[v=\sqrt{\frac{T}{\mu }}\] \[\therefore \] \[v=\sqrt{\frac{10}{0.1}}\] \[v=\sqrt{100}=10\,m/s\]You need to login to perform this action.
