    The correct vector relation between linear velocity \[\vec{v}\] and angular velocity \[\vec{\omega }\] in rigid body dynamics is ( where \[\vec{r}\] is the postion vector)

    A)  \[\vec{\omega }=\vec{v}\times \vec{r}\]

    B)  \[\vec{v}=\vec{r}/\vec{\omega }\]

    C)  \[\vec{v}=\vec{\omega }\times \vec{r}\]

    D)  \[\vec{r}=\vec{v}\times \vec{\omega }\]

    Correct Answer: C

    Solution :

    The vector relation between linear velocity \[\vec{v}\] and angular velocity \[\vec{\omega }\] in rigid body dynamics is \[\vec{v}=\vec{\omega }\times \vec{r}\].
