Two parallel  plate air capacitance  `C`, were connected  in series  to a battery with  `emf  xi`. Then one of the capacitors was filled  up with uniform dielectric  with permittivity  `epsilon`. How many  times did the electric field strength  in that capacitor decrease ? What amount of charge  flows  throgh  the battery ?
