Problem

A rigid body rotates with constant angular velocity

\omega

about the line whose vector equation is,

\mathbf{r} = \lambda(\hat{i} + 2\hat{j} + 2\hat{k})

. The speed of the particle at the instant it passes through the point with position vector

(2\hat{i} + 3\hat{j} + 5\hat{k})

is equal to a.

\omega\sqrt{2}

2\omega

\omega/\sqrt{2}

d. None of these
