  It is known that two Reissner-Nordstrom black holes or two overextreme
Reissner-Nordstrom sources cannot be in physical equilibrium. In the static
case such equilibrium is possible only if one of the sources is a black hole
and another one is a naked singularity. We define the notion of physical
equilibrium in general (stationary) case when both components of a binary
system are rotating and show that such system containing a Kerr-Newman black
hole and a Kerr-Newman naked singularity also can stay in physical equilibrium.
The similar question about the system of two charged rotating black holes or
two rotating overextreme charged sources still remains open.
