A) \[1.68\text{ }V,\text{ }0.47\text{ }A\]
B) \[~0\text{ }V,\text{ }0.47\text{ }A\]
C) \[5.6\,V,1.4\,A\]
D) \[0\,V,\,1.4\,A\]
Correct Answer: C
Solution :
\[R=\frac{{{\varepsilon }_{0}}{{n}^{2}}{{h}^{2}}}{\pi \,m\,z\,{{e}^{2}}}\] \[V=\frac{z{{e}^{2}}}{2{{\varepsilon }_{0}}n\,h}\] \[E=-\frac{m\,{{z}^{2}}{{e}^{4}}}{8{{\varepsilon }_{0}}^{2}{{n}^{2}}{{h}^{2}}}\] \[V/E\propto n\] \[RV\propto n\]
