Friction Basics
Given below are two statements:
Statement (I): The limiting force of static friction depends on the area of contact and independent of materials.
Statement (II): The limiting force of kinetic friction is independent of the area of contact and depends on materials.
In the light of the above statements, choose the most appropriate answer from the options given below:
Show answer and solution
Answer: (a)
- Statement I: limiting static friction does not depend on area of contact and does depend on the materials (through ), so it is incorrect.
- Statement II: kinetic friction is independent of area and depends on the materials, so it is correct.
- So the answer is (a).
