In a meter-bridge experiment with a resistance` R_(1)` in left gap and a resistance X in a right gap. null point is obtained at 40 cm from the left emf. With a resistance `R_(2)` in the left gap, the null point is obtainned at 50 cm from left hand. Find the position of the left gap is containing` R_(1) and R_(2)` in series.
