In this case yes, but if q1 was -20μC, q2 was 30μC, and r was 0.5m, then using -20μC as it is would make F equal to -21.6N which is just 21.6N of attraction force between the two charges.

    If they are oppositely charged particles, I would expect that there is a force of attraction acting on them, yes.

    I am not saying that's wrong, just that there's 21.6N of attraction force between the two charges not -21.6N.

    But those are the same thing.
