In an experiment to determine an unknown resistance, a 100 cm long resistance wire is used. The unknown resistance is kept in the left gap and a known resistance is put into the right gap. The scale to measure length has a least count 1 mm. The null point B is obtained at 40.0 cm from the left gap. We shell determine the percentage error in the computation of unknown resistance.

To determine the percentage error in the computation of the unknown resistance using the given information, we can follow these steps: ### Step 1: Understand the Setup We have a 100 cm long resistance wire. The unknown resistance (let's call it \( x \)) is placed in the left gap, and a known resistance (let's call it \( y \)) is placed in the right gap. The null point is found at 40.0 cm from the left gap. ### Step 2: Define the Lengths Let: - \( L_1 = 40.0 \) cm (the length from the left gap to the null point) ...
