A uniform ladder of length Land weighing W, leans up against a well making an angle S with the horizontal, as shown in the figure below. A monkey weighing Ww climbs a distance d up the ladder and stops. The distance d is measured from the bottom of the ladder, along the ladder's length, to the point where the monkey stops. The upper and lower ends of the ladder rest on frictionless surfaces. The lower end is connected to the wall by a horizontal rope whose tension is T. 11. What is the expression for the normal force due to the touch of the wall on the ladder (N.) in terms of the other forces acting on the ladder? a. N.=T b. N=0 C. New=Ner d. Now = W Rape 12. Consider an axis of rotation at the top of the ladder and perpendicular to the page. What is the magnitude of the torque exerted on the ladder by the weight of the monkey? a. L"Ww"'sin(90-0) b. (L-o]"Walni90-8) c. d"Wa'sIn(90-8) d. d*W."sin(90+8)
