The electrohydrodynamic phenomena associated with the motion of a charged particle in a plasma are investigated. It is shown that the type of disturbance produced in the plasma depends significantly on the speed of the particle, i.e., whether it is subsonic, transonic, or supersonic. In the subsonic case, the electrohydrodynamic drag experienced by the particle is caused by an unsymmetric wake formed by the screening electrons. In the supersonic case, electron screening is confined to the Mach cone. Ahead of the Mach cone, the plasma behaves as if it were an incompressible fluid. The electrohydrodynamic drag in this case has a logarithmic nature.
