Use either image charge method of separation of variables to solve: The distance between two large, grounded parallel conducting plates is 4x. Between them, two point charges +Q and -Q are inserted and have a distance x and 3x from one of the plates. (A line connecting the two charges is perpendicular with the plates) The basic principle of the method of images is the uniqueness theorem. As long as (1) the solution satisfies Poissonʼs or Laplaceʼs equation and (2) the solution satisfies the given boundary condition, the simplest solution should be taken. 3.5 Method of Images Point charge over grounded plane conducto

Edit: Apologies for incomplete details. From the text, which is discussing the method of images for point charges and planes: A charge placed near the corner of two intersecting plates has images not only behind each of the conducting planes, but each of the images in turn has an image in the other planes and so on, very much like an optical image shifted by the plate in a plane parallel with image plane. As shown in Fig 2, the 3D point P is shifted to point P¢ by the plate and the displacement is denoted as R. The image points of P and P¢ through the projection center C are p and p 1 respectively. The displacement of P in image space is the distance between p and p 1 and is denoted as r

The capacitance of a parallel plate capacitor is proportional to the area, A in metres 2 of the smallest of the two plates and inversely proportional to the distance or separation, d (i.e. the dielectric thickness) given in metres between these two conductive plates. The generalised equation for the capacitance of a parallel plate capacitor is given.
