A block rests on a rough horizontal plane and a force P is applied to the block as shown. 
The normal reaction between the plane and the block is N and the frictional force between the block and the plane is F. The coefficient of static friction between the block and the plane is μS and initially P is zero.
As P is increased in value, which one of the following statements is true concerning the relationship between F, N and μS ? 

• F is always equal to μ_SN
  
• F is always greater than μ_SN 
• F is always less than μ_SN
  
• F can be equal to μ_SN
