The mass of a uniform ladder of length 5m is 20kg . A person of mass 60kg stand on the ladder at a height of 2m from the bottom. The position of centre of mass of the ladder and man from the bottom is

As shown in Fig. the two sides of a step ladder BA and CA are 1.6 m long and hinged at A . A rope DE, 0.5 m is tied half way up. A weight 40 kg is suspended from a point F, 1.2 m from B along the ladder BA . Assuming the floor to be fricionless and neglecting the weight of the ladder, find the tension in the rope and forces exerted by the floor on the ladder. (Take g = 9.8 m//s^(2)) (Hint. Consider the eqilibrium of each side of the ladder separately.)
