A) \[\frac{p-{{p}_{1}}}{{{p}_{2}}-p}\]
B) \[\frac{{{p}_{2}}-p}{p-{{p}_{1}}}\]
C) \[\frac{p+p}{p+{{p}_{2}}}\]
D) \[\sqrt{\frac{{{p}_{1}}{{p}_{2}}}{p}}\]
Correct Answer: B
Solution :
[b] \[V\,pg={{V}_{1}}{{p}_{1}}+{{V}_{2}}{{p}_{2}}g\,\therefore \,V={{V}_{1}}+{{V}_{2}}\] \[({{V}_{1}}+{{V}_{2}})\,pg={{V}_{1}}{{p}_{1}}+{{V}_{2}}{{p}_{2}}g\] \[{{V}_{1}}pg+{{V}_{2}}pg={{V}_{1}}{{p}_{1}}g+{{V}_{2}}{{p}_{2}}g\] \[{{V}_{1}}+{{V}_{2}}p={{V}_{1}}{{p}_{1}}+{{V}_{2}}{{p}_{2}}\] \[\frac{{{V}_{1}}}{{{V}_{2}}}=\frac{{{P}_{2}}-P}{p-{{p}_{1}}}\]You need to login to perform this action.
