# Negative electric potential

I am studying about electric potential, and in particular electric potential around a point charge, by the formula we get that:

$$V_E=\frac{1}{4\pi\epsilon_0}\frac{Q}{r}$$

My question is: Can the potential be negative? i.e. if the point charge is of some negative charge, say $-P$ is it true that $V_E=-\frac{1}{4\pi\epsilon_0}\frac{P}{r}$, or $V_E=\frac{1}{4\pi\epsilon_0}\frac{|-P\ |}{r}=\frac{1}{4\pi\epsilon_0}\frac{P}{r}$.

Furthermore when dealing with two charges and the potential energy $U_E=qV$, is it $|q|$ or $q$ itself ?

Yes, the potential and the potential energy ($U=qV$, not with a $|q|$) can be negative.
