The inner surfaces to A and C can be connected to earth through plate D and keys K1 and K2 . The plates D is a dielectric slab with dielectric constant K1 then the charge that will flow through plate D and keys K1 and K2 . The plate D is a dielectric slab with dielectric constant K, then the charge that will flow though plate D when K2 is closed and K2 is open is
