A) Rolling < static < sliding friction
B) Static > sliding > rolling friction
C) Static > rolling > sliding friction
D) Sliding < static < rolling friction
Correct Answer: B
Solution :
For the given surfaces static friction is somewhat greater than sliding friction as well as-rolling friction. It is easier to roll than to slide. Hence, sliding friction is greater than rolling friction. The decreasing order of magnitude of friction is static, sliding and rolling.
