A potentiometer is connected between $A$ and $B$ and the balance point is obtained at $203. 6\,cm$. When the end of the potentiometer connected to $B$ is shifted to $C$, then the balance point is obtained at $24.6\,cm$. If now the potentiometer be connected between $B$ and $C$, the balance point will be at ................. $cm$

$e_1 = 203.6$ $....(i)$
$e_1 -e_2 = 24.6$ $...(ii)$
$(i) - (ii)$ gives $e_2 = 179.0\,cm$
