The motion of a dust-particle cloud in the afterglow of a complex plasma is reported. It is shown that the dust-particle charges strongly affect the dynamic behavior of the dust cloud. Consequently, using the analysis of the whole cloud motion to deduce dust residual-charge and plasma-diffusion parameters is proposed.
