The length of a potentiometer wire is \(l\). A cell of emf \(E\) is balanced at a length \(l / 3\) from the positive end of the wire. If the length of the wire is increased by \(l / 2\). At what distance will the same cell give a balance point? π²PW App Link - https://bit.ly/YTAI_PWAP πPW Website - https://www.pw.live
