A) \[\frac{2\pi }{15}Nm\]
B) \[\frac{\pi }{12}Nm\]
C) \[\frac{\pi }{15}Nm\]
D) \[\frac{\pi }{10}Nm\]
Correct Answer: C
Solution :
As\[\tau =I\alpha =I\left( \frac{{{\omega }_{0}}-\omega }{t} \right)\] \[\tau =\frac{2\times 2\pi \times 60}{60\times 60}\] \[=\frac{\pi }{15}N/m\]You need to login to perform this action.
