Two perfect dielectrics have relative permittivities r1 = 2 and r2 = 8. The planar
Question:
Two perfect dielectrics have relative permittivities ∈r1 = 2 and ∈r2 = 8. The planar interface between them is the surface x − y + 2z = 5. The origin lies in region 1. If E1 = 100ax + 200ay − 50az V/m, find E2.
