# Math Help - Hookes law

1. ## Hookes law

I just sat an exam and wondered if i attempted this question correctly.

it said a spring had force keeping it compressed (i forget the figures) and basically i had to find the modulus of elesticity

so say the force was 800N, would i do this -

$800=\frac{\lambda x}{l}$

or

$800=\frac{\lambda x^2}{2l}$

or neither... i'm doomed lol

2. Hi

Hookes lay says: $F=k\cdot x$ , where k is the constant you are looking for, and x the distance the spring is compressed or extended.

Solve for k.
