Consider the configuration shown in the figure: An in- finite plane conductor has a small hemispherical knob of radius a as indicated. A point charge q is placed directly to the right hand side of the hemispherical knob at a distance b from its center. Assume that the boundary, i.e. the infinite plane with the knob, is kept at zero potential. a) Find the potential p at a generic point P on the right hand side. b) Determine the appropriate Dirichlet Green function for this geometry and write down the most general solution of the potential p given a generic charge density p on the right hand side of the boundary and that potential p = f("r) on the boundary. %3D c) Find the total charge induced on the knob. P(r) a b
