A block of weight 100 N is suspended by copper and steel wires of same cross sectional area `0.5 cm^(2)` and, length `sqrt(3)` m and 1m, 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 `(Delta l_(C))` and elongation in steel wire is `(Delta l_(s))`, then the ratio `(Delta l_(C))/(Delta l_(s))` is -

[Young's modulus for copper and steel are `1 xx 10^(11) N//m^(2) and 2 xx 10^(11) N//m^(2)`, respectively]
