Given below are two statements: Statement I: The maximum value of static friction \( (f_s)_{\text{max}} \) is independent of the area of contact between surfaces. Statement II: The coefficient of kinetic friction \( \mu_k \) is generally slightly greater than the coefficient of static friction \( \mu_s \). In the light of the above statements, choose the most appropriate answer from the options given below:

  1. A
    Statement I is correct but Statement II is incorrect.
  2. B
    Both Statement I and Statement II are correct.
  3. C
    Both Statement I and Statement II are incorrect.
  4. D
    Statement I is incorrect but Statement II is correct.
View Answer & Solution

Correct answer · Option A

Statement I is correct but Statement II is incorrect.

Explanation

Statement I is correct because limiting static friction depends on normal reaction and surface nature, not contact area. Statement II is incorrect because kinetic friction coefficient \( \mu_k \) is usually less than static friction coefficient \( \mu_s \).
