A wheel of radius R rolls on the ground ...

A wheel of radius `R` rolls on the ground with a unifrom velocity `v`. The velocity of topmost point releative to bottom must point is

A

zero

B

`2 upsilon`

C

`upsilon`

D

`upsilon//2`

Text Solution

Verified by Experts

The correct Answer is:
B
In Fig.

At the bottom most point `L`,
`v = R omega`
At the topmost point `H`
`v' = r omega = 2R omega = 2v`
