There is a vertical tension at the top of a 4 m long ladder holding it at an incline. The bottom of the ladder is touching the floor, which exerts a normal force. You are standing 1 meter from the top of the ladder. What happens to the tension as you walk up the ladder? As you walk down the ladder? As the angle between the ladder and the ground decreases? Why?
