In a potentiometer circuit a cell of EMF \(1.5 \mathrm{~V}\) gives balance point at \(36 \mathrm{~cm}\) length of wire. If another cell of EMF \(2.5 \mathrm{~V}\) replaces the first cell, then at what length of the wire, the balance point occurs ?
(A) \(60 \mathrm{~cm}\)
B) \(21.6 \mathrm{~cm}\)
c \(64 \mathrm{~cm}\)
D \(62 \mathrm{~cm}\)
