Answer #1

Hooke's Law states that the force required to maintain a spring stretched x meters beyond its natural length is kx

Let the natural length of spring be L. Then we can write, for the force being experienced in both cases,

To solve, we divide (1) by (2)

Now we find the distance by which spring is moved beyond its natural state
