5 Be careful when climbing a ladder! A ladder of weight $W_L$ leans against a wall. The ladder has rollers at the top so that the wall exerts only a normal force on the top of the ladder. A person of weight $W_P$ slowly climbs the ladder. A free-body diagram for the ladder is shown ($W_P$ actually act on the person, not the ladder, but because of the person moving very slowly, the force they do on the ladder happens to have the same magnitud as their weight). As the person ascends the ladder, the normal force $F_Y$ from the floor on the ladder A. Increases B. Decreases C. Increases until they reach the middle point and then decreases D. Decreases until they reach the middle point and then increases E. Stays the same all throughout
