A body is rotating with angular velocity

\omega = \left( {3\hat i - 4\hat j - \hat k} \right)

. The linear velocity of a point having position vector

r = \left( {5\hat i - 6\hat j + 6\hat k} \right)

is

View answer and explanation

Correct option: C

- 30\hat i - 23\hat j + 2\hat k

Option C (

- 30\hat i - 23\hat j + 2\hat k

) is correct because the linear velocity is calculated using the cross product of angular velocity and position vector:

v = \omega \times r

.
