A parallel plate capacitor has plates of area A separated by distance ' 
'. It is filled with a dielectric which has a dielectric constant varies as 
, where ' 
' is the distance measured from one of the plates. If 
, the capacitance of the system is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
D
Given, 
Since all capacitance are in series, we can apply
On putting the limits from 0 to 
Using expression 
And putting 
where, 
approaches to 0 .
