How do you konw if dipole movement is negative or positive?

Let's say you have 2 charges of magnitude 2C except 1 is + and the other -. They're separated by 2m. dipole moment=p=qL

Which q do you plug in there?

The formula you quote is for a dipole consisting of two charges: +q and -q. Therefore, you plug in the magnitude of the charges q, which is positive by definition.
