A) 1.4\[\Omega \]
B) 1.6\[\Omega \]
C) 0.12\[\Omega \]
D) 1.2\[\Omega \]
Correct Answer: D
Solution :
Consider a cell of emf E and balanced by length \[_{\text{5}}{{\text{Y}}^{\text{10}}}{{\text{=}}_{\text{5}}}{{\text{B}}^{\text{10}}}\] \[{{E}_{n}}=-\frac{13.6}{{{n}^{2}}}eV\] The potential difference is balanced length \[\Rightarrow \] \[34=-\frac{13.6}{{{n}^{2}}}\] The intemal resistance of the cell is given by \[\Rightarrow \] \[{{n}^{2}}=4\] \[\Rightarrow \]
