Question

A Spring stretches by 10 cm when a force of 20N is applied .When a force of 22N is used the spring stretches by 11 cm . What would be the extension for force of 10N,1N,5N,15N?

Answer 1

Answer:

The extension for force of 10N,1N,5N,15N is 5cm,0.5cm,2.5cm,and 7.5cm respectively.

Step-by-step explanation:

The extension for force of 20N=10 cm

The extension for force of 1N=10/20 =1/2cm

That is =0.5cm

The extension for force of 10N=10/20×10

That is = 5cm

The extension for force of 5N=1/2×5

That is =5/2 cm

That is =2.5cm

The extension for force of 15N=1/2×15

That is =15/2cm

That is =7.5cm
