A body of mass m is kept on a rough horizontal surface (coefficient of friction = 
). A horizontal force is applied on the body, but it does not move. The resultant of normal reaction and the fractional force acting on the object is given by F, where F is,
= mg
= mg + 
mg
= 
mg

Now, for the given case the body does not move
Hence, we can say that body is in equilibrium,
Consider
frictional force which is less than or equal to limiting friction = f r
Normal force = N
Horizonal force = F
Coefficient of friction = 
Now,
N = mg
