A composite bar made up of steel (Modulus of elasticity = E) is hanging freely under its own weight as shown in the figure below. Self weight and cross sectional area of RQ bar are 2W and 2A respectively while those of PQ bar, are W and A respectively. Considering self weights of the bars, the displacement of point P is (a) 2WL/3AE (b) 3WL/2AE (c) 5WL/2AE (d) WL/AE
