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 \( 2.5 \mathrm{~V} \)
P replaces the first cell, then at what length of the wire, the

W) balance point occurs?
\( (2021) \)
(a) \( 21.6 \mathrm{~cm} \)
(b) \( 64 \mathrm{~cm} \)
(c) \( 62 \mathrm{~cm} \)
(d) \( 60 \mathrm{~cm} \)
