Two cells of emf `E_(1) ` and `E_(2)` are to be compared in a potentiometer `(E_(1) gt E_(2))` . When the cells are used in series correctly , the balancing length obtained is 400 cm. When they are used in series but `E_(2)` is connected with reverse polarities, the balancing obtaiend is 200cm. Ratio of emf of cells is
