Three plates A, B and C are placed close to each other with +Q charge given to the middle plate. The inner surfaces to A and C canbe connected to earth through plate D and keys K_(1) and K_(2) . The plates D is a dielectric slab with dielectric constant K_(1) then the charge that will flow through plate D and keys K_(1) and K_(2) . The plate D is a dielectric slab with dielectric constant K, then the charge that will flow though plate D when K_(2) is closed and K_(2) is open is |
