Query: The Structure of the Pseudo-Newtonian Force and Potential about a Five
  Dimensional Rotating Black Hole   In this paper we investigate the structure of the pseudo-Newtonian force and
potential about a five dimensional rotating black hole. The conditions for the
force character from an attractive to repulsive are considered. It is also
found that the force will reach a maximum under certain conditions.
