Step 1: Use V = Σ[kqᵢ/rᵢ] for discrete charges or integrate dV = k dq/r for a continuous distribution. If a field is given, use ΔV = -∫𝐄·d𝐥. Step 2: Potential is a scalar, so contributions add algebraically. Step 3: Insert the stated distances/charge distribution and simplify. Final: Option B. In this specific setup, apply the calculation to: Eight charges, each of the magnitude q are placed at the vertices of a cube placed in vacuum. Electric po.
