Solution
The correct option is A Static friction > Sliding friction > Rolling friction
- When a body is sliding, its contacting surface does not get enough time to lock onto the contact points of the other surface. Therefore, sliding produces less friction as compared to static friction.
- It is always easier to roll a body over another than slide it. So, rolling friction is further less than sliding friction.
- Ultimately, the correct order is given as: Static friction > Sliding friction > Rolling friction.
