Figure `6.49` shows a circuit that may be used to compare the resistance `R` of an ubknown resistor with a `100 Omega` standard. 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`?
