In a meter bridge experiment with resistance R₁ in left gap and resistance X in right gap, null point is obtained at 40 cm from left end. With a resistance R₂ in left gap and same resistance X in right gap, null point is obtained at 50 cm from left end. Where will be null point if R₁ and R₂ are put first in series and then in parallel, in the left gap and eight gap still containing X?
