The plasma force on grains of specified charge and height in a collisional DCplasma sheath are calculated using the multidimensional particle in cell codeCOPTIC. The background ion velocity distribution functions for the unperturbedsheath vary substantially with collisionality. The grain force is found toagree quite well with a combination of background electric field force plus iondrag force. However, the drag force must take account of the non-Maxwellian(and spatially varying) ion distribution function, and the collisional dragenhancement. It is shown how to translate the dimensionless results intopractical equilibrium including other forces such as gravity.
