One end of the steel rod is clamped to the roof and the other end is attached to a mass of 1000kg as shown in the figure. The length of the rod is 50cm and its cross-sectional area is 1000mm2. The change in the length of the rod due to the weight of the mass is (Young's modulus of steel =2×1011Nm−2 and acceleration due to gravity =10ms−2 )
