Potential energy is U = kQq/r Where r is the distance between them, Q and q are the charges and k is a constant ( = 1 / (4 * pi * E0) .... E0 is the permittivity of free space) In the equation all you're doing is replacing Q with -Q, which just flips the sign once you multiply and you're left with -U1. It will be -U1.
