357264 On interchanging the resistances, the balance point of a meter bridge shifts to the left by 10 \(cm\). The resistance of their series combination is 1 \(k\Omega \). How much was the resistance on the left slot before interchanging the resistances?

1 \(505\,k\Omega \)
2 \(550\,k\Omega \)
3 \(910\,k\Omega \)
4 \(990\,k\Omega \)

357265 Assertion :
In a Metre Bridge experiment, null point for an unknown resistance is measured. Now, the unknown resistance is put inside an encloser maintained at a higher temperature. The null point can be obtained at the same point as before by decreasing the value of the standard resistance.
Reason :
Resistance of a metal increases with increase in temperature

1 Both assertion and reason are correct and reason is the correct explanation of assertion.
2 Both assertion and reason are correct but reason is not the correct explanation of assertion.
3 Assertion is correct but reason is incorrect.
4 Assertion is incorrect but reason is correct.

357267 In a metre-bridge experiment, when the resistances in the gaps were interchanged, the balance-point did not shift at all. The ratio of resistances must be

1 Very large
2 Very small
