## Homework Statement

A wire of unstretched length l is extended by a distance (1/1000)l when a mass M is hung from its bottom end. If this same wire is connected between points A and B that are at a distance l from each other on the same horizontal level, and the mass M is hung from the midpoint of the wire, find the depression y of the midpoint.

## Homework Equations

2Tsin(theta) = mg

sin(theta) = y/(the stretched length of l/2).

## The Attempt at a Solution

Not sure where to go from there. Would it be safe to say that each half of the wire is stretched by l/2000? Thanks.
