In the solution given in the above image, I am unable to understand and prove why

*N*

_{1}=f and

*N*

_{2}=W. I have tried balancing the torque on different point but still unable to prove. Explain how

*N*

_{1}=f and

*N*

_{2}=W can be proved.

The justification for

*N*

_{1}=f and

*N*

_{2}=W which I have so far read is that it is just balancing the vertical force with vertical force and the horizontal force with horizontal force which are being applied on the object since the object is at equilibrium. My confusion with that is that the vertical and horizontal forces are being applied at different position of the object, how can they be directly compared so that the ladder is in equilibrium.
