1. Imagine you lean a ladder against the leaning tower of pisa, whose walls are tilted further than vertical. If you wanted the normal force from flat ground to be the minimum, would you lean the ladder against the side pitched towards you, side pitched away from you, the side pitched sideways from you, or would not matter which side?

A. side pitched sideways B. side pitched towards you C. side pitched away from you D. it doesn't matter which side.

I have uploaded the image with all the three condition. Here is the cofficient of friction of wall of tower and N is the normal reaction of wall of the tower. Since , therefore R is lower in the third image. Which means that normal force from the ground would be minimum when ladder is lean against the side piched sideways.
