The comments of Riemann and van den Berg represent a misinterpretation of what was presented by Zawaideh {ital et} {ital al}. (Phys. Fluids {bold B} {bold 2}, 647 (1990)). Namely, they claim that the oscillations in the electric field in the presheath region are a result of incorrect boundary conditions. To disprove their claim, both the sheath and presheath region with no assumption about quasineutrality have been solved self-consistently. To eliminate the issue of incorrect boundary conditions, a symmetrically confined plasma between two floating electrodes was considered. From the self-consistent solution, it is shown that, for subsonic flow, the oscillations in the electric field do exist in the absence of external particle sources and are not due to an incorrect boundary condition.
