A body is in pure rotation. The linear speed 'v' of a particle, the distance 'r' of the particle from the axis and the angular velocity `omega` of the body are related as `omega=v/r`. Thus

A

`omega prop (1)/(r)`

B

`omega prop r`

C

`omega =0`

D

`omega` is independent of r.

Text Solution

Verified by Experts

The correct Answer is:
D

If `r` be the distance of point from axis will increase, then corresponding `v` of the point will also increase accordingly, Hence, `omega` is constant.
