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 (sinθ−μcosθ) to P2=mg (sinθ+μcosθ), the frictional force f versus P graph will look like

A uniform rope of length l resting on a frictionless horizontal surface is pulled at one end by a force F. What is the tension in the rope at a distance l from the end where the force is applied?
