Electrostatic Potential and Capacitance - Result Question 29

31. 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 : [2014]

(a)

(b)

(c)

(d)

Show Answer

Answer:

Correct Answer: 31. (c)

Solution:

  1. (c) Electric field, E1K

As K1<K2 so E1>E2

Hence graph (c) correctly dipicts the variation of electric field E with distance d.
