A parallel plate capacitor with plate area 'A' and distance of separation 'd' is filled with a dielectric. What is the capacity of the capacitor when permittivity of the dielectric varies as : `epsi(x)=epsi_(0)+kx`, for `(0ltxle(d)/(2))`
`epsi(x)=e_(0)+k(d-x)`, for `(d/2lexled)`

A

`(epsi_(0)+("kd")/(2))^(2//"kA")`

B

`("kA")/(2ln""((2epsi_(0)+"kd")/(2epsi_(0))))`

C

0

D

`("kA")/(2)"ln"((2epsi_(0))/(2epsi_(0)-"kd"))`
