Question

A ladder of length 10 m and mass 20 kg (and with uniform mass distribution) leans against a slippery vertical wall. The ladder makes an angle of 30° with respect to the vertical. Friction between the ladder and the ground prevents it from sliding downwards. What is the magnitude of the force exerted on the ladder by the wall? [Take √(3) = 1.732; g = 10 m/s^2] A. 0 N B. 0.58 N C. 58 N D. 5.8 N

Step 1

The forces are: - The weight of the ladder (W) acting vertically downward at the center of mass. - The normal force (N) exerted by the ground acting vertically upward. - The frictional force (F_f) exerted by the ground acting horizontally to the right. - The Show more…
