Force of Attraction between two ions?

  1. Feb 14, 2009 #1
    1. The problem statement, all variables and given/known data
    Calculate the force of attraction between Ca2+ and O2- ions whose centers are separated by 1.25 nm.



    3. The attempt at a solution Well, I belive this is a matter of electrostatic force (Coulomb's Law)...but I am not sure what to use for the values of q1 and q2
    Is it just the elementary charge multiplied by 2 for each ion (since they both have a net charge of 2)?

    Is this the right idea?
