Question

A force of 10 N extends a spring by 3cm. What will be the extension if a mass of 0.3kg is attached to the lower end of the spring?

Answer 1

Answer:

Explanation: spring force = 1/2 K x

As given 1/2k(0.03) = 10

k = 20/0.03

When mass will be attached and hanged then spring force = mass of block × g

1/2 k x = 0.3 × 10

1/2 (20/0.03) x = 0.3 × 10

x = 0.3 × 0.03

x = 0.009
