With a certain unknown resistance X in the left gap and a resistance of 8ohm in the right gap, null point is obtained on the metre bridge wire. On putting another 8ohm in parallel with 8ohm resistance in the right gap, the null point is found to shift by 15cm. Find the value of X from these observations.
