A) \[\frac{5}{8}\]
B) \[\frac{4}{5}\]
C) \[\frac{5}{4}\]
D) \[\frac{4}{7}\]
Correct Answer: C
Solution :
[c] \[\frac{{{I}_{e}}}{{{I}_{h}}}=\frac{{{n}_{e}}eA{{v}_{e}}}{{{n}_{h}}eA{{v}_{h}}}\Rightarrow \frac{7}{4}=\frac{7}{5}\times \frac{{{v}_{e}}}{{{v}_{h}}}\Rightarrow \frac{{{v}_{e}}}{{{v}_{h}}}=\frac{5}{4}\]You need to login to perform this action.
