Region 2 (z < 0) contains a dielectric for which , = 2.5. Region 1 (z > 0) has Er = 4 as shown in the sketch below. 1 Er1 = 4, E₁, D₁ Er2 = 2.5, E₂, D₂ If E₂ = -30a, + 50a, +70a, V/m, (a) Draw the vector diagram and show the normal, tangential, and E, electric field in region 2. (3) Determine: 2 (b) (c) z = 0 the angle between E₂ and the normal to the surface in region 2. the energy density in region 2. (5) (3) (4) (d) the polarization P in region 2. units Let V = 3x² and € = Eo. Given the point P(1,2,-1), determine (a) the volume charge density p, in free space. (4) (b) the equation of the equipotential surface passing through point P. (3) P² اله-١٢
