A ring rolls without slipping on the ground. Its centre `C` moves with a constant speed `u.P` is any point on the ring. The speed of `P` with respect to the ground is `v`.

A

`0 le v le 2u`

B

`v = u`, if `CP` is horizontal

C

`v = u`, if `CP` makes an angle of `30^@` with the horizontal and `P` is below the horizontal level of `C`.

D

`v = sqrt(2 u)`, if `CP` is horizontal.

Text Solution

Verified by Experts

The correct Answer is:
A, C, D
(A)
`omega = (u)/( R)`
If point `P` is at heighest point than
`v_(p) = omega xx 2R`
`v_(p) = 2 u`
If point `P` is in contact with ground
`v_(p) = 0`
`0 lt V_(p) lt 2 u`.
( C) When `CP` is horizontal
`v_(p) = R omega`
`v_(p) = u`
ltbgt (D)
`v_(p) = omega xx sqrt(2) R`
`v_(p) = sqrt(2) u`.
