Question
Assertion: Static frictional force may be greater than kinetic frictional force.Reason: Static frictional force is always equal to $\mu_{s} N$ $(N=$ normal reaction $)$(A) $\mathrm{A}$(B) $\mathrm{B}$(C) $\overline{\mathrm{C}}$(D) D
Step 1
This can be represented as $f_{s} \leq \mu_{s} N$, where $f_{s}$ is the static frictional force, $\mu_{s}$ is the coefficient of static friction, and $N$ is the normal reaction. Show more…

The maximum static friction on a body is $F=\mu N$. Here, $N=$ normal reaction force on the body $\mu=$ coefficient of static friction The dimensions of $\mu$ is : (a) $\left[\mathrm{MLT}^{-2}\right]$ (b) $\left[\mathrm{M}^{n} \mathrm{~L}^{0} \mathrm{~T}^{n} \theta^{-1}\right]$ (c) dimensionless (d) none of these
