Different types of Forces

A block of mass 0.1 kg is held against a wall by applying a horizontal force of 5 N on the block. If the coefficient of friction between the block and the wall is 0.4, the magnitude of the frictional force acting on the block is 


Limiting frictionFl=μsR=0.4×(5)=2.0 N
Since downward force is less than limiting friction therefore block is at rest so the static force of friction will work on it.
Fs= downward force = Weight
