Laws Of Motion

In the figure, a ladder of mass m is shown leaning against a wall. It is in static equilibrium making an angle \(\theta\) with the horizontal floor. The coefficient of friction between the wall and the ladder is \(\mu\)₁ and that between the floor and the ladder is \(\mu\)₂. The normal reaction of the wall on the ladder is N₁ and that of the floor is N₂. If the ladder is about to slip, then
