A) \[\text{2s}\]
B) \[\pi \text{s}\]
C) \[2\pi \text{s}\]
D) \[1\text{s}\]
Correct Answer: B
Solution :
\[\left| a \right|={{\omega }^{2}}y\] \[\Rightarrow 20={{\omega }^{2}}(5)\] \[\Rightarrow \omega =2rad/s\] \[T=\frac{2\pi }{\omega }=\frac{2\pi }{2}=\pi s\]You need to login to perform this action.
