Question 2

A uniform wooden stick of mass 1.6 kg and length / rests in an inclined manneron a smooth, vertical wall of height A(</) such that a small portion of the stick extends beyond the wall. The reaction force of the wall on the stick is perpendicular to the stick. The stick makes an angle of $$30^\circ$$ with the wall and the bottom of the stick is on a roughfloor. The reaction of the wall on the stick is equal in magnitudeto the reaction of the floor on the stick. The ratio h/l and thefrictional force f at the bottom of the stick are (g = 10 ms$$^2$$)
