The given circuit shows a uniform straight wire \(AB\) of \(40 ~\text{cm}\) length fixed at both ends. In order to get zero reading in the galvanometer \(G,\) the free end of \(J\) is to be placed from the end \(B\) at:
1. \(32~\text{cm}\)
2. \(8~\text{cm}\)
3. \(16~\text{cm}\)
4. \(24~\text{cm}\)

A Wheatstone bridge is used to determine the value of unknown resistance \(\mathrm{X}\) by adjusting the variable resistance \(\mathrm{Y}\) as shown in the figure. For the most precise measurement of \(\mathrm{X}\), the resistances \(\mathrm{P}\) and \(\mathrm{Q}\):
| 1. | do not play any significant role. |
| 2. | should be approximately equal to \(2\mathrm{X}\). |
| 3. | should be approximately equal and are small. |
| 4. | should be very large and unequal. |
