A block of mass m is on an inclined plane of angle $θ$. The coefficient of friction between the block and the plane is $μ$ and $tanθ>μ$. The block is held stationary by applying a force P parallel to the plane. The direction of force pointing up the plane is taken to be positive . As P is varied from $P_{1}=mg(sinθ−μcosθ)$ to $P_{2}=mg(sinθ+μcosθ)$ the frictional force f versus P graph will look like
