A) \[\frac{m{{r}^{2}}}{6\pi \eta }\]
B) \[\sqrt{\left( \frac{6\pi mr\eta }{{{g}^{2}}} \right)}\]
C) \[\frac{m}{6\pi \eta rv}\]
D) None of these
Correct Answer: D
Solution :
[d] \[F=6\pi \eta rv\] \[\Rightarrow mg=6\pi \eta rv\](dimensionally) Check options dimensionallyYou need to login to perform this action.
