Question
When a resistor of \(5 \Omega\) is connected across the cell, its terminal potential difference is balanced by \(150 cm\) of potentiometer wire and when a resistance of \(10 \Omega\) is connected across cell, the terminal potential difference is balanced by \(175 cm\) same potentiometer wire. Find the balancing length when the cell is in open circuit and the internal resistance of the cell.
