Charging mechanism of dust grain in a plasma

Summary form only given. Recent observation in space and solar physics and in plasma technologies has led to further studies in dusty plasma. Recently many interesting experimental has been studied viz. formulation of dust crystals, dust clouds and dust leviation etc. There are number of reviews covering all aspects of the physics of dusty plasma. In the last decade the collective modes in dusty plasma was mainly investigated and little attention has been paid on the formation of kinetic equation for changing of the dust grain, transport properties of dusty plasmas etc. In this paper we try to develop a kinetic equation for charging of the dust grain.
