How far from a -7.20-C point charge must a +2.30-C point charge be placed for the electric

Question:

How far from a -7.20-µC point charge must a +2.30-µC point charge be placed for the electric potential energy U of the pair of charges to be -0.400 J? (Take U to be zero when the charges have infinite separation.)
