Two identical parallel plate capacitors, of capacitance C each, have plates of area A, separated by a distance d. The space between the plates of the two capacitors, is filled with three dielectrics, of equal thickness and dielectric constants K1, K2 and K3. The first capacitor is filled as shown in fig. I, and the second one is filled as shown in fig II. If these two modified capacitors are charged by the same potential V, the ratio of the energy stored in the two, would be (E1 refers to capacitor (I) and E2 to capacitor (II)):

Next Question :
The following question consists of two statements I and II are given below. You have to decide whether the data provided in the statements are sufficient to answer the question.
What is the average of the best and worst score out of 8 tests taken by a student?
I. The average of all 8 tests is 84%.
II. After dropping the best and worst grade, the average of remaining 6 tests is 86%
(a) The data in statement I alone was sufficient to the answer the question while II alone not sufficient to the answer the question.
(b) Data in statement II alone are sufficient to answer the question while data in statement I alone are not sufficient to answer the questions.
(c) The data in statement I alone or in statement II alone are sufficient to answer the questions.
(d) The data in both statements I and II are sufficient to answer the question.
