Question

A ody 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.

Answer 1

Correct Answer - 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.
