A wardrobe (mass 100 kg, height 4 m, width 2 m, depth 1 m), symmetric about the Y-axis, stands on a rough level floor as shown in the figure. A force P is applied at mid-height on the wardrobe so as to tip it about point Q without slipping. What are the minimum values of the force (in newton) and the static coefficient of friction ^_$\mu$ between the floor and the wardrobe, respectively?
