A block of mass m is laying on an inclined plane of angle θ. If the friction co–efficient between the block and the plane is θ and tan θ > µ and the block is held stationary by applying a force P parallel to the plane and the direction of force pointing up the plane is taken to be positive. As P is varied from P1 = mg (sin θ − µcosθ) to P1 = mg (sinθ + µcosθ) then the frictional force f versus P graph will be
