Homework Statement
A block of mass M is hung on a vertical spring.
We have to find spring constant k, x (displacement from mean position) given.
Homework Equations
1/2kx^2 = mgx
mg=kx
The Attempt at a Solution
When i conserve energy,
1/2kx^2=mgx
⇒ k= 2mg/x
But when i use mg=kx,
I get k=mg/x
But mg/x≠2mg/x,
Help please :)
