Question

A meter bridge is set up as shown in figure, to determine an unknown resistance ‘X’ using a standard 10 ohm resistor. The galvanometer shows null point when tapping - key is at 52 cm mark. The end-corrections are 1 cm and 2 cm respectively for the ends A and B. The determined value of ‘X’ is

10.2 ohm
10.6 ohm
10.8 ohm
11.1 ohm

The correct answer is: 10.6 ohm
