• # question_answer Two points of a rod move with velocities 3v and v perpendicular to the rod and in the same direction, separated by a distance r. Then the angular velocity of the rod is A)  $3v/r$                         B)  $4v/r$C)  $5v/r$                         D)  $2v/r$

${{\omega }_{rod}}={{\omega }_{po\operatorname{int}}}=\left( \frac{{{v}_{nel}}}{r} \right),$${{v}_{rel}}$ represents the velocity of one point w.r.t. other. $=\frac{3v-v}{r}$ and 'r' being the distance between them.$=\frac{2v}{r}$
