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:

Step-by-step explanation:

Weight = 150gm

produced extension = 2.9 cm

So, Weight produce when an extension will be 17.4 cm be x gm.

----------------------------------------------------------

WEIGHT (in gms) | 150 | x |

----------------------------------------------------------

EXTENSION (in cms) | 2.9 | 17.4 |

----------------------------------------------------------

SO, ATQ, ( According to the question)

→ 150/2.9 = x/17.4

→ 150×17.4 = 2.9x

→ 2.9x = 2610

→ x = 2610/2.9

→ x = 900

So, X= 900

Therefore,the weight produce an extension of 17.4 cm = 900 gms.
