Question

Which of the following is the correct relation between linear velocity $\vec{v}$ and angular velocity $\vec{\omega }$ of a particle?

• A. $\vec{v}=\vec{r}\times \vec{\omega }$
• B. $\vec{v}=\vec{\omega }\times \vec{r}$
• C. $\vec{\omega }=\vec{r}\times \vec{v}$
• D. $\vec{\omega }=\vec{v}\times \vec{r}$

Answer 1

Answer: (B)

The relation between linear velocity $\vec{v}$ and angular velocity $\vec{\omega }$ is $\vec{v}=\vec{\omega }\times \vec{r}$
