QNEET-2018-Ph-896: NEET 2018 Physics - Class 11 NEET-2018-Ph-896 Solution: Which one of the following statements is incorrect? Rolling…
Which one of the following statements is incorrect? Rolling friction is smaller than sliding friction. Limiting value of static friction is directly proportional to normal reaction. Frictional force opposes the relative motion. Coefficient of sliding friction has dimensions of length.
Multiple Choice Options
- A Rolling friction is smaller than sliding friction.
- B Limiting value of static friction is directly proportional to normal reaction.
- C Frictional force opposes the relative motion.
- D Coefficient of sliding friction has dimensions of length.
Step-by-Step Verified Solution
We know,
F = _ N
_ MLT �2 = _ MLT �2
_ _ = M 0 L 0 T 0
_ Coefficient of sliding friction has no
dimension.
