Vedclass · Answer

(B) The maximum static frictional force,also known as limiting friction,is given by the formula $f_{max} = \mu_s N$,where $\mu_s$ is the coefficient of static friction and $N$ is the normal force.Since the normal force $N$ depends on the weight of the object $(N = mg)$ and the coefficient of static friction $\mu_s$ depends on the nature of the materials in contact,the maximum static frictional force does not depend on the apparent area of the surfaces in contact.Therefore,the maximum static frictional force is independent of the area of the surface in contact.
