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