Question

A block of mass $m$ is kept on a horizontal table. If the static friction coefficient is $\mu$, find the frictional force acting on the block.

Answer 1

Here, block is kept stationary and no any force is acting except gravitational force.

Hence the frictional force on block of mass m will be zero.

However, the max frictional force can be

$f_{max}=\mu N=\mu mg$
