Two thin dielectric slabs of dielectric constants K1 and K2 ( K1 < K2) 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 ?

Two thin dielectric slabs of dielectric constants K1 and K2 ( K1 < K2) 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)

Answer :  (c)

\( E_{\text{eff}} = E_{\text{external}} - E_{\text{internal}} \)

\( K \text{ larger means } E_{\text{internal}} \text{ higher} \)
