A) \[\sqrt{aR}\]
B) \[\frac{1}{\sqrt{aR}}\]
C) \[aR\]
D) \[\frac{1}{aR}\]
Correct Answer: A
Solution :
\[{{v}_{e}}\propto \sqrt{gR}\] Given\[\frac{{{R}_{1}}}{{{R}_{2}}}=R\]and\[\frac{{{g}_{1}}}{{{g}_{2}}}=a\] \[\therefore \] \[\frac{{{({{v}_{e}})}_{x}}}{{{({{v}_{e}})}_{y}}}=\sqrt{\frac{{{g}_{1}}{{h}_{1}}}{{{g}_{2}}{{h}_{2}}}}=\sqrt{aR}\]
