Question

In the experimental setup of metre bridge shown in the figure, the null point is obtained at a distance of 40cm from A. If a 10Ω resistor is connected in series with R₁, the null point shifts by 10cm. The resistance that should be connected in parallel with (R₁ + 10)Ω
such that the null point shifts back to its initial position is:
(A) 20Ω (B) 40Ω
(C) 60Ω (D) 30Ω
