Question

the amount of extension in an elastic spring varies as the weight hung on it . if a weight of 150 g produces extension of 2.9 cm, then what weight would produce an extension of 17.4cm​

Answer 1

Answer:

the weight of the object in extension of 2.9 cm is 150 gm

then the weight in 17.4 cm extension is 150*17.4/2.9=900

Answer 2

Answer:

900gm

Step-by-step explanation:

let the weight required be x gm

extension(cm)=2.9      17.4

weight (gm)=   150        x

2.9/150=17.4/x

on cross multiplication,we get

2.9*x=150*17.4

x=150*17.4/2.9

x=900

therefore the weight in grams=900gm
