NEET Physics Friction Assertion Reason Question
Assertion (A): The kinetic frictional force experienced by an object is independent of the velocity of the object.
Reason (R): Once the relative motion between surfaces begins, the kinetic frictional force decreases from the static maximum value.
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
According to the NCERT context, kinetic friction is nearly independent of velocity, which makes Assertion (A) true. However, Reason (R) describes the transition from static to kinetic friction, not the independence of velocity, making R a true statement on its own but not a correct explanation for A.
