A) \[\frac{r_{2}^{2}}{r_{1}^{2}}\]
B) \[\frac{{{r}_{2}}}{{{r}_{1}}}\]
C) \[\frac{r_{1}^{2}}{r_{2}^{2}}\]
D) \[\frac{{{r}_{1}}}{{{r}_{2}}}\]
Correct Answer: A
Solution :
According to equation of continuity \[{{A}_{1}}{{v}_{1}}={{A}_{2}}{{v}_{2}}\] or \[\frac{{{v}_{1}}}{{{v}_{2}}}=\frac{{{A}_{2}}}{{{A}_{1}}}=\frac{r_{2}^{2}}{r_{1}^{2}}\]You need to login to perform this action.
