A block of weight 100 N is suspended by copper and steel wires of same cross sectional area 0.5 cm and, 60 length 3 m and 1 m, respectively. Their other ends are fixed on a ceiling as shown in figure. The angles subtended by copper and steel wires with ceiling are 30 and 60, respectively. If elongation in copper wire is (Alc) and elongation in steel wire is (Als), then the ratio is Als [Young's modulus for copper and steel are 1 10 N/m and 2 10 N/m, respectively.] Steel wire 1m Block 3m 30 Copper wire
