A rigid body is rotating with angular velocityabout an axis of rotation. Let ‘v’ be the linear velocity of particle which is at perpendicular distance ‘r’ from the axis of rotation. Then the relation ‘v’ =implies that
Options:
Answer:
A
Solution:
Using the given relation,
If the perpendicular distance r from the axis of rotation is increased or decreased, then the value of linear velocity v accordingly increases or decreases. Thus, the value of angular velocitydoes not depend on r.
