Q18. Two infinitely extended homogeneous isotopic dielectric media (medium-l and medium-2 with dielectric constant = 2 and2 =5 , respectively) Eo So medium - 1 meet at the z 0 plane as shown in the figure. A uniform electric field exists everywhere. For z 2 0, the electric field medium-2 z=0 is given by E, = 2i-3+5k. The interface separating the two media is charge free. The electric displacement vector in the medium-2 1s given by (a) D =610 +15+ 10R (b) D,-,loi - 157- 106 (c) Da =6o 4i -6j+ 10OR d) D - 4i+6j+ 10 Ans: (b)
