In the figure, a ladder of mass m is shown leaning against a wall. It is in static equilibrium making an angle 
with the horizontal floor. The coefficient of friction between the wall and the ladder is 
1 and that between the floor and the ladder is 
2 . The normal reaction of the wall on the ladder is N 1 and that of the floor is N 2 . If the ladder is about to slip, then
