Is it possible to have an arrangement of two point charges separated by finite distances such that the electric potential energy of the arrangement is the same as if the two charges were infinitely far apart? What if there are three charges?

Two point charges Q and -Q/4 are separated by a distance x.

Three charges -q,+Q and -q are placed in a straight line as shown If the total potential energy of the system is zero, then the ratio (q)/(Q) is

Charges -q , Q, and -q are placed at an equal distance on a straight liner. If the total potential energy of the system of three charges is zero, then find the ratio Q//q . .
