The distance l from one end of the potentiometer slider wire to the balance point are 400 mm and 588 mm when X is connected to Y and Z, respectively. The length of the slide wire is 1.00 m. What is the value of resistance R?

if one decides to balance a resistance of 4X against Y? In a meter bridge experiment the null point is obtained at 20 cm from one end of the wire when resistance X is balanced against another resistance Y. If X< Y then where will the new position of the null point be from the same end
