A) \[\eta \,r\]
B) \[\eta \,{{r}^{2}}\]
C) \[{{\eta }^{2}}r\]
D) \[\frac{{{r}^{2}}}{\eta }\]
Correct Answer: D
Solution :
Terminal velocity of a spherical ball in a viscous liquid, \[{{\upsilon }_{t}}=\frac{2}{9}\frac{(p-\sigma ){{r}^{2}}g}{\eta }\propto \frac{{{r}^{2}}}{\eta }\]You need to login to perform this action.
