A LADDER OF LENGTH 4m weighing 300N is placed against vertical wall . the coefficient of friction between the wall and the ladder is 0.3.The ladder in addition to its own weight has to support a man weiging 600N at a distance of 3m from A. Calculate the minimum horizontal force to be applied at A to prevent slipping.
