Query: Classification for the radial component of particles motion in the field
  of a super-extremely charged object   A method for investigation of neutral test particles motion with the angular
momentum L in the Reissner-Nordstr\"om field of a super-extremely charged
object with mass M and charge Q > M is proposed. The problem of classifying the
radial component of motion is reduced to working up a classification for
"effective" potential types and subsequent consideration of trajectories for
each of these types.
