Equilibrium of a Particle: Finding the Unstretched Length of a Spring

[edwinandrew]

Homework Statement

The question are included in the picture that are uploaded. So i know that for these systems to be at equilibrium, the net force in the x and y-axis must equal to zero. I wanted to write in the question and the diagram but i don't know how else to put it.

Homework Equations

F=ks, ∑F _x=0, ∑F_y=0

The Attempt at a Solution

I tried breaking it down into components for x and y but i don't know what value to use to determine the unstretched length of the spring.[/B]
