4-2.Friction
medium
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:
A
Statement $I$ is correct but Statement $II$ is incorrect
B
Statement $I$ is incorrect but Statement $II$ is correct
C
Both Statement $I$ and Statement $II$ are incorrect
D
Both Statement $I$ and Statement $II$ are correct
(JEE MAIN-2024)
Solution
Co-efficient of friction depends on surface in contact So, depends on material of object.
