A one-dimensional approach to study the plasma sheath profiles in the presheath and sheath regions of a colloidal plasma was discussed. The ions and dusts were assumed to be adiabatic fluid with finite temperature in the absence of a source and electrons were assumed to be Boltzmannian. To explore the possible physical solutions, the set of equations were solved numerically for the presheath and the sheath regions. In continuity, solutions for presheath and sheath regions were obtained. The solutions for three distinct cases for both interacting and noninteracting dust were analyzed using combined effects of electrostatic, neutral drag and external gravity forces.
