Question: Let the cylindrical surfaces = 4 cm and = 9 cmenclose two wedges of perfect dielectrics, r1 = 2 for 0 <

Let the cylindrical surfaces ρ = 4 cm and ρ = 9 cmenclose two wedges of perfect dielectrics, ∈_r1 = 2 for 0 < ϕ < π/2 and ∈_r2 = 5 for π/2 < ϕ < 2π. If E1 = (2000/ρ)a_ρ V/m, find

(a) E₂;

(b) The total electrostatic energy stored in a 1 m length of each region.
