The horizontal component is 0.72 N to the right.

The amount of static friction is inversely proportional to the amount of normal force and the degree of roughness between the sliding surfaces. The friction coefficient is calculated by dividing the frictional force's magnitude by the force's normal force.

The applied force must be greater than the friction force since the net force is to the right (in the direction of the applied force). Understanding net force as the vector sum of all the forces can help you calculate the friction force.

Given , F = 1.2 N and mass = 1 kg

we will you F - цN = ma ------- 1

and equate it with the equation ma = mg + N

After substituting the values

We will get the value of acceleration as 0.4 [tex]m/s^2[/tex]

Substitute this value in equation 1

A force is basically the interactions between bodies, these interactions creates binding energy between two surfaces that can be formed and broken too, the friction force is the macroscopic sum of all these microscopic interactions between two different surfaces. The magnitude of the friction force is dependent on the type of surface, if we talk about rough surface, the interaction area is high, therefore the frictional force will be high, whereas on smooth surfaces the interaction area is small, therefore the force is small.
