The area of parallel plates of an air capacitor is  `0.2 m^(2)` and the distance  between them is `0.01m` The potential  difference  between  the plates, the potential  difference  between  the plates is  `3000 V`. When  a `0.01 m` thick sheet of an insulating  material is placed  between  the plates, the potential  difference   decrease to 1000 volt. Determine  (i) capacitance  of capacitance before placing the sheet  (ii) charge on each plate (iii) dielectric constant  of material  (iv) capacitanc after placing the insulator (v) absoulate permittivity of the dielectric.
