Question
Download Solution PDFA body of weight 100 N is lying on a rough horizontal surface, and the horizontal force of 50 N is applied on the body as shown in the figure, which is just enough to move the body. What will be the coefficient of friction?

Friction-
- Sliding friction can be defined as the resistance created by any two objects when sliding against each other.
- This friction is also known as kinetic friction and is defined as the force that is needed to keep a surface sliding along another surface.
- It depends on two variables- one is material and the other is the weight of the object. Any change in the surface area in contact does not change the sliding friction.
-
The equation for sliding force includes the coefficient of sliding friction times the normal force.
Fs = μFn
Where FS = force of sliding friction,Fn = normal force , μ = Coefficient of sliding friction
Given data and calculation-
Body weight = Fn = 100 N
Friction force = 50 N
Coefficient of friction =
