Four charges of 6μC, 2μC, − 12μC and 4μC are placed at the corners of a square of side 1m. The square is in x-y plane and its center at its origin. Electric potential due to these charges is zero everywhere on the line -

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: C: x = 0 = y.
