Two thin dielectric slabs of dielectric constants K 1 and K 2 (K 1 < K 2 ) are inserted between plates of a parallel plate capacitor, as shown in the figure. The variation of electric field 'E' between the plates with distance 'd' as measured from plate P is correctly shown by:
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
Electric field inside parallel plate capacitor having charge Q at place where dielectric is absent 
where dielectric is present 
As 
so 
Hence graph correctly depicts the variation of electric field E with distance d.
