When a resister of 10Omega is connected ...

When a resister of `10Omega` is connected across a cell, its terminal potential difference is balanced by 150cm of potentiometer wire and when `20Omega` resistance is connected across the cell, terminal potential difference is balanced by 175cm of the same potentiometer wire. Find the balancing length when the cell is in open circuit and also find the internal resistance of the cell.
