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 tan θ > 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 P1 = mg (sin
θ – μ cos θ) to P2 mg (sin θ + μ cos θ), the frictional force f is
