In a potentiometer arrangement, a cell gives a balancing point at $\displaystyle 75$ cm length of wire. This cell is now replaced by another cell of unknown emf. If the ratio of the emf's of two cells respectively is $\displaystyle 3$ : $\displaystyle 2$, the difference in the balancing length of the potentiometer wire in above two cases will be \_\_\_\_ cm.
