Problem
Three points A, B and C lie on the same straight line extending outward from an isolated point charge +Q such that OA = 1 cm, OB = 2 cm and OC = 3 cm (O is the position of the charge). Without performing any numerical calculation, arrange the magnitudes of the electric fields at A, B and C in ascending order and justify your answer in one sentence.
