A) \[\frac{1}{2}\]
B) \[\frac{1}{4}\]
C) \[\frac{1}{3}\]
D) \[1\]
Correct Answer: B
Solution :
As, pressure difference, \[{{P}_{B}}-{{P}_{O}}=\frac{2T}{3R}\] ?..(i) and \[{{P}_{A}}={{P}_{B}}+\frac{2T}{R}\] ??(ii) From equations (i) and (ii), we get \[{{P}_{A}}-{{P}_{O}}=\frac{2T}{3R}+\frac{2T}{R}=2T\left[ \frac{4}{3R} \right]\] \[\Rightarrow \] \[\frac{{{P}_{B}}-{{P}_{O}}}{{{P}_{A}}-{{P}_{O}}}=\frac{1}{4}\]You need to login to perform this action.
