A disc is rolling (without slipping) on ...

A disc is rolling (without slipping) on a horizontal surface. `C` is its center and `Q` and `P` are two points equidistant from `C`. Let `V_(P), V_(Q)` and `V_(C)` be the magnitude of velocities of points `P, Q` and `C` respectively, then
.

A

`V_(Q)gtV_(C)gtV_(P)`

B

`V_(P)gtV_(C)gtV_(Q)`

C

`V_(Q)=V_(P),V_(C)=V_(P)//2`

D

`V_(P)ltV_(C)ltV_(Q)`

Text Solution

Verified by Experts

The correct Answer is:
C
Here `v_(P)=sqrt(V^(2)+omega^(2)r^(2))`
`V_(Q)=sqrt(V_(c)^(2)+omega^(2)+2V_(c)omegarcostheta)`
