Homework Help: Moon exchange particle

  1. Nov 9, 2014 #1
    1. The problem statement, all variables and given/known data
    If an exchange particle held the moon together, what would the mass of the exchange particle be?
    Moon radius = 1737 km

    2. Relevant equations
    Well, I know that the range of an exchange particle is as follows: [itex]R=\frac{\hbar}{2mc}[/itex] where m is the mass of the exchange particle and c is speed of light, hbar is 1.054e-34.
    3. The attempt at a solution
    I do not fully understand what a range is....how can I apply a range to this problem? If I could figure that out, i think I would be able to figure the problem out
