Query: Exact Harmonic Metric for a Moving Reissner-Nordstr\"om Black Hole   The exact harmonic metric for a moving Reissner-Nordstr\"om black hole with
an arbitrary constant speed is presented. As an application, the post-Newtonian
dynamics of a non-relativistic particle in this field is calculated.
