A) \[2\pi r{{p}_{2}}gh\]
B) \[\frac{{{p}_{2}}rgh}{2}\]
C) \[\frac{r}{2}\,({{p}_{2}}-{{p}_{1}})gh\]
D) \[2\pi r\,({{p}_{2}}-{{p}_{1}})gh\]
Correct Answer: C
Solution :
From the Bernoulli?s equation \[{{P}_{0}}+h{{p}_{1}}g-{{p}_{2}}gh+\frac{2T}{r}={{P}_{0}}\] \[T=\frac{r}{2}\,({{p}_{2}}-{{p}_{1}})\,\,gh\]You need to login to perform this action.
