Blocks shown in figure have been placed on a smooth horizontal surface and mass of (n + 1)^(th) block is (1)/(20) times the mass of n^(th) block (where n=1,2,3,4,…. ). The first block is given an initial velocity u towards the second block. All collision are head on elastic collisions. If u = 10 m//s then how many blocks must be kept so that the last one acquires speed equal to or greater than the escape speed (=11.0 km s^(-1)) [Take log_(10)((40)/(21))=0.28 and log_(10)(11)=1.04 ]

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]
