Equipotential surfaces shown in the figure are equidistant, parallel and have equal potential difference between two consecutive surfaces.This information is clear indication of uniform electric field which is given as

∣ E \to ∣ = - \frac{Δ V}{Δ r} = \frac{20 - 10}{BC} = \frac{10}{10 s in 3 0 ^{\circ}}

∴ E = \frac{10}{5} = 2 V / c m
