Ans. 135.5a, V/m; 305 nC; 965 nC. D3.3. Given the electric flux density, D = 0.3r2a, nC/m² in free space: (a) find E ...A 2 cos θ = A 1. Because the same number of field lines crosses both S1 S 1 and S2 S 2, the fluxes through both surfaces must be the same. The flux through S2 S 2 is therefore Φ = EA1 = EA2 cosθ. Designating ^n2 as a unit vector normal to S2 (see Figure 6.4 (b)), we obtain. Φ =→E ⋅^n2A2.Dimensional Formula of Electric Flux. The dimensional formula of electric flux is given by, [M 1 L 3 T-3 I-1] Where, M = Mass; I = Current; L = Length; T = Time; Derivation. Electric Flux (Φ E) = E × S × cos θ . . . . (1) Where E = magnitude of the electric field and S = Surface Area. The dimensional formula of area (S) = [M 0 L 2 T 0 ....
