NEET Physics Friction Assertion Reason Question
Assertion (A): Kinetic friction is generally less than static friction. | Reason (R): Kinetic friction is independent of the area of contact between surfaces.
Both A and R are true, and R is the correct explanation of A.
Both A and R are true, but R is not the correct explanation of A.
A is true, but R is false.
A is false.
Correct Answer
Detailed Explanation
Both statements are true; however, kinetic friction being less than static friction is due to the nature of the forces and not because it is independent of the area of contact.
