Force of Attraction between two ions?

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?
