A) \[a\omega \]
B) \[\sqrt{3}\,a\omega \]
C) \[\sqrt{2}\,a\omega \]
D) \[2\,a\omega \]
Correct Answer: C
Solution :
\[{{V}_{x}}=a\omega sin\omega t\] \[{{V}_{y}}=a\omega cos\omega t\] \[{{V}_{z}}=a\omega \] \[\left| V \right|=\sqrt{V_{x}^{2}+V_{y}^{2}+V_{z}^{2}}\] \[=\,\sqrt{{{a}^{2}}{{\omega }^{2}}\,{{\sin }^{2}}\,\omega t+{{a}^{2}}{{\omega }^{2}}\,{{\cos }^{2}}\,\omega t\,+{{a}^{2}}\,{{\omega }^{2}}}\] \[\left| V \right|\,\,=\,\,\sqrt{2}\,a\omega \]You need to login to perform this action.
