The centre of a wheel rolling on a plane surface moves with a speed v0. A particle on the rim of the wheel at the same level as the centre will be moving at speed
  1. Zero
  2. v0
  3. 2v0
  4. 2v0

As per question,
The speed of the centre of wheel =vo
Particle is on the rim of the wheel,
So,
The situation can be shown as in the diagram
Here v0=Rω
At P,v=rω
=(R2+R2)ω=2Rω=2v0
So the speed of the particle is on the rim =2Rω
