A 200-N block A rests on a wedge B of negligible weight, as shown in the figure.
The coefficient of static friction is the same on both surfaces of the wedge and the
friction between the block and the vertical wall can be neglected thanks to the three
rollers shown. If we know that P = 100 N. How much is the coefficient of friction if
instead of the rollers there is a wall rough and the value of the coefficient of static
friction is the same between all surfaces. (Note, wedge B rests on the floor).
