## Homework Statement

## Homework Equations

## The Attempt at a Solution

I really don't know how to start with this problem. The four point masses of mass m oscillate together so I am confused as to how should I begin making the equations. Just a guess, should I write down the expression for potential energy of the system?

Any help is appreciated. Thanks!
