Step 1: Electric field is perpendicular to equipotential surfaces and points from higher to lower potential: 𝐄 = -∇V. Step 2: Closer equipotential spacing means larger |E|; field-line density likewise represents field strength. Step 3: Read the relative spacing/direction from the figure. Final: B: -100 V m⁻¹, + 200 V m⁻¹.
