Two painters are working from a wooden hoard 5 m long suspended from the top of a building by two ropes attached to the ends of the plank. Either rope can withstand a maximum tension of 1040N. Painter A of mass 80kg is working at a distance of 1m from one end. Painter B of mass 60kg is working at a distance of x in from the centre of mass of the board on the other side. Take mass of the board as 20 kg and g = 10 m/s^2. The range of x so that both the painters can work safely is
