In an experiment to measure the internal resistance of a cell by potentiometer, it is found that the balance point is at a length of `2 m` when the cell is shuntedd by a `5 Omega` resistance, and is at a length of `3 m` when the cell is shunted by a `10 Omega` resistance. The internal resistance of the cell is, then
