NEET Physics Friction Assertion Reason Question
Assertion (A): Kinetic friction is independent of the area of contact between two surfaces.
Reason (R): The coefficient of kinetic friction depends only on the surfaces in contact, not on the area of contact.
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, but R is true.
Correct Answer
Detailed Explanation
The NCERT context states that kinetic friction is independent of the area of contact and that the coefficient of kinetic friction depends only on the nature of the surfaces in contact.
