A) \[\frac{V{{R}^{2}}}{{{n}^{3}}{{r}^{2}}}\]
B) \[\frac{{{V}^{2}}R}{nr}\]
C) \[\frac{V{{R}^{2}}}{{{n}^{2}}{{r}^{2}}}\]
D) \[\frac{V{{R}^{2}}}{n{{r}^{2}}}\]
Correct Answer: D
Solution :
[d] Apply equation of continuity \[{{A}_{1}}{{v}_{1}}={{A}_{2}}{{v}_{2}}\] \[\pi \,{{R}^{2}}V=n\pi {{r}^{2}}u\] \[u=\frac{V{{R}^{2}}}{n{{r}^{2}}}\]You need to login to perform this action.
