A) \[\frac{\sqrt{6}}{2}\]
B) \[\sqrt{24}\]
C) 3
D) \[\frac{\sqrt{3}}{2}\]
Correct Answer: B
Solution :
[b] \[{{v}_{e}}=\sqrt{2{{g}_{e}}{{R}_{e}}};={{v}_{m}}=\sqrt{2{{g}_{m}}{{R}_{m}}}\] \[\frac{{{v}_{e}}}{{{v}_{m}}}=\sqrt{\frac{{{g}_{e}}}{{{g}_{m}}}\frac{{{\operatorname{R}}_{e}}}{{{R}_{m}}}}=\sqrt{\frac{{{g}_{e}}}{{{g}_{e}}/6}\frac{{{\operatorname{R}}_{e}}}{{{\operatorname{R}}_{e}}/4}}=\sqrt{24}\]
