Henriksen, R. N. ; Norton, J. A. Abstract The force-free axisymmetric pulsar magnetosphere is examined with the inertial effects of a two-fluid plasma taken into account. Strictly speaking, only electrostatic acceleration is possible. This is not the case, however, for charged particles which are constrained to flow along rigidly-corotating force-free magnetic field lines. The integrals of motion and the electromagnetic constraints together yield an algebraic set that describes completely this constrained particle acceleration, which is found as a function of boundary conditions at the surface of the star. This solution may emulate the inertial particle acceleration of the oblique rotator. 'Inertial sling' solutions, yielding particles with high accelerations and corotationally dominated motion, are possible only in magnetospheres for which the poloidal component of the magnetic field dominates sufficiently close to the light cylinder (unless the field is swept forward). The general theory is applied numerically and analytically to a two-fluid rotating monopole. Electrostatic acceleration is found not to be significantly responsible for particle acceleration in this case.
