| 95% | Derive E for infinite line/plane via Gauss's law — Use the 5-step template above. State law, draw, symmetry, flux, enclosed charge, solve. | 5 MARKS |
| 85% | Coulomb's law numerical with 3 charges in triangle/square — Find each pairwise force, resolve, use vector/parallelogram law. | 3 MARKS |
| 70% | Dipole field on axial OR equatorial line — Set up geometry, use Coulomb's law on each charge, superpose, take r ≫ a limit. | 3 MARKS |
| 80% | Define flux + find flux through closed surface — Gauss's law directly: Φ = q_enclosed/ε₀, regardless of surface shape. | 2 MARKS |
| 50% | Find null point on line joining two charges (E = 0) — Set E from +q = E from −q on the line; closer to the smaller charge for like, between the two for unlike. | 3 MARKS |
