A) 5/\[\pi \]
B) 1/\[\pi \]
C) 10\[\pi \]
D) 20\[\pi \]
Correct Answer: A
Solution :
Angular velocity \[\omega =2\,rad/s\] \[2\pi n=2\] \[n=\frac{2}{2\pi }=\frac{1}{\pi }\] Number of revolution in \[1\sec =\frac{1}{\pi }\] Number of revolution in \[5\sec =\frac{5}{\pi }\]You need to login to perform this action.
