Q. Figure below shows a circuit which may be used to compare the resistance $R$ of an unknown resistor with a $100\Omega$ standard. The distances $l$ 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 is 1.00 m. What is the value of resistance R?

1. $32\Omega$
2. $47\Omega$
3. $68\Omega$
4. $147\Omega$
