In a laboratory experiment on friction a block of weight 135 N lying on a rough horizontal table is pulled by a horizontal wire The pull P gradually increases until the block begins to move and continues to increase thereafter Given figure shows a graph of the friction force on this block as a function of the pull P The regions of the graph where the static friction occur is from f N 75 50 25 0 25 50 75 100 1 P ON to P 100 N 2 P 0 N to P 75 N 3 P 75 N to P 100 N 4 Only at P 75 N P N
