- Thedynamical charging of dust grains is an important process andis found to enhance the shielding of a test chargepassing through a multi-component dusty plasma. In the present work,the energy loss of a test charge projectile passing througha dusty plasma in the presence of dynamical grain chargingis studied. The electric forces can be written in termsof the Maxwell stress tensor for a sphere around thetest charge. For sphere with radius tending to zero theforce is just that on the test charge. For afinite radius, forces on the plasma are also included whichmakes it possible to see how the force on thetest charge is balanced by the force on the plasma.The method fails for the zero radius but the dragforce can be found from a simple physical model. Thegeneral analytical results are presented and are compared with theprevious results.
