Two point P and Q. diametrically opposite on a disc of radius R have linear velocities v and 2v as shown in figure. Find the angular speed of the disc.

A

`v/R`

B

`2v/R`

C

`v/(2R)`

D

`v/4R`

Text Solution

Verified by Experts

`omega=-(v_(r))/(PQ)=(2v-v)/(2R)=(v)/(2R)`
Rotation is clockwise So, `omega` is perpendicular to paper inward.
