Rotational Motion Question 135

Question: 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 ‘. The angular velocity of the rod is

Options:

A) 3vr

B) 4vr

C) 5vr

D) 2vr

Show Answer

Answer:

Correct Answer: D

Solution:

[d]

ωrod =(Vrel )r(Vrel ) is me velocity of one point w.r.t.

other perpendicular to rod.

ωrod=3vvr And ‘r’ being the distance between the points.

ωrod=2vr
