Query: Scalar and electromagnetic fields of static sources in higher
  dimensional Majumdar-Papapetrou spacetimes   We study scalar massless and electromagnetic fields from static sources in a
static higher dimensional spacetime. Exact expressions for static Green's
functions for such problems are obtained in the background of the
Majumdar-Papapetrou solutions of the Einstein-Maxwell equations. Using this
result we calculated the force between two scalar or electric charges in the
presence of one or several extremely charged black holes in equilibrium in the
higher dimensional spacetime.
