Homework Help: Mass places o that it is in equilibrium

  1. Dec 15, 2013 #1
    1. The problem statement, all variables and given/known data

    A mass,M, is fixed at a position of 3m. Another mass, 2M, is fixed at the position -1m. What position(s) can a third mass, 3M, be placed so that it is in equilibrium.

    2. Relevant equations

    The only thing I could think of is M(3)+2M(-1)+3Mx=0

    3. The attempt at a solution

    I tried the center of mass equation and got the same wrong answer.

    So that what is in equilibrium? I believe you are missing part of the question.
