A parallel plate capacitor having a separation between the plates d, plate area A and material with dielectric constant K has capacitance `C_(0)`. Now one-third of the material is replaced by another material with dielectric constant 2K, so that effectively there are two capacitors one with area 1/3A, dielectric constant 2K and another with area 2/3A and dielectric constant K. If the capacitance of this new capacitor is C then `(C)/(C_(0) `is

A

1

B

`4//3`

C

`2//3`

D

`1//3`
