In the formula of finding electric flux, Ө is the angle between the E and the area vector (ΔS). 5.You may conceptualize the flux of an electric field as a measure of the number of electric field lines passing through an area . The larger the area, the more field lines go through it and, …Expert Answer. Given that: Internal Radius of the sphere r i n = 0.2 m. Outer Radius of the sphere r o u t = 0.25 m. Initial Surface Charge Density on sphere surface σ 1 = + 6.37 × 10 − 6 C m 2. Charge inside the cavity Q = − 0.500 μ C = − 0.5 × 10 − 6 C. Area of the sphere A = 4 π r 2..
