A 2.2m of steel wire hangs vertically down from a support. A 1.5m length of brass wire of the same diameter is attached to the lower end of the steel wire.when a 10 kg mass is attached to the lower end of the brass wire a total extension of 0.05 m is produced. by how much does each wire extend? (young's modulus for steel = 2.0 x 10^11pa, young's modulus for brass = 9.2 x 10^10 pa)
