A potentiometer wire is $\displaystyle 100$ cm long and a constant potential difference is maintained across it. Two cells are connected in series first to support one another and then in opposite direction. The balance points are obtained at $\displaystyle 50$ cm and $\displaystyle 10$ cm from the positive end of the wire in the two cases. The ratio of emf's is :
