Given below are two statements: Statement I: Static friction is a self-adjusting force that increases up to a maximum limit \( f_{s,\max} = \mu_s N \). Statement II: The maximum value of static friction depends strongly on the total area of contact between the two surfaces. In the light of the above statements, choose the most appropriate answer from the options given below:

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

Correct answer · Option C

Statement I is correct but Statement II is incorrect.

Explanation

Static friction is self-adjusting up to \( f_{s,\max} = \mu_s N \), but experimentally the limiting friction is independent of the area of contact.
