Step 1: Use superposition, 𝐄 = Σ[1/(4πε₀)] qᵢ 𝐫ᵢ/rᵢ³, or the appropriate continuous-distribution integral. Step 2: Resolve components and exploit symmetry to cancel components. Step 3: Add the surviving components and compare with the choices. Final: Option B. In this specific setup, apply the calculation to: Figure below shows regular hexagon, with different charges placed at the vertices. In which of the follow.
