The ion drag force and charge on a spherical dust grain located in RF discharge plasma is computed using a 3-dimensional Particle-Particle Particle-Mesh (P3M) code. Our plasma model includes finite-size effects for dust grains and allows to self-consistently resolve the dust grain charging due to absorption of plasma electrons and ions. Ion drag and dust charge have been computed for various sizes of dust particles placed at various locations in the discharge. The results for ion drag have been compared with previous collisionless models and affect of collisions on drag has been discussed in detail.
