Physics · SYSTEMS OF PARTICLES AND ROTATIONAL MOTION

हिन्दी

A rigid body is undergoing general planar motion that is a combination of translation and rotation. If at an instant the angular velocity vector is \( \vec{\omega} \) and the linear velocity of point \( A \) is \( \vec{v}_A \), then the linear velocity \( \vec{v}_B \) of any other point \( B \) separated by relative position vector \( \vec{r}_{BA} \) is given by:

  1. A
    \( \vec{v}_B = \vec{v}_A - \vec{\omega} \times \vec{r}_{BA} \)
  2. B
    \( \vec{v}_B = \vec{\omega} \times \vec{r}_{BA} \)
  3. C
    \( \vec{v}_B = \vec{v}_A + \vec{\omega} \times \vec{r}_{BA} \)
  4. D
    \( \vec{v}_B = \vec{v}_A + \vec{r}_{BA} \times \vec{\omega} \)
View Answer & Solution

Correct answer · Option C

\( \vec{v}_B = \vec{v}_A + \vec{\omega} \times \vec{r}_{BA} \)

Explanation

In relative kinematics of a rigid body, the velocity of point \( B \) is the vector sum of translation velocity of \( A \) and rotation of \( B \) about \( A \): \( \vec{v}_B = \vec{v}_A + \vec{\omega} \times \vec{r}_{BA} \).
