φ3 = flux through curved surface So, φ1 = ∮E*dA*cos ⁰⁰ ………..[Direction between E and dA is ⁰⁰] or, φ1 = ∮E*dA or, φ1 = E ∮dA ……………[Because E is constant] ∮dA is the surface area of bases = A . So, the equation becomes : φ1 = E * A For lower base , the equations are the same . So, φ2 = E * A For the
