A) 9.6 m
B) 7.5 m
C) 4.4 m
D) 3.2 m
E) None of the Above
Correct Answer: E
Solution :
According to equations, \[p\left( \frac{h}{2} \right)=\frac{1}{3}p(h)\] \[\left( 1\,atm+\rho g\frac{h}{2} \right)=\frac{1}{2}\left( 1\,atm+\rho gh \right)\] \[3\,atm+\frac{3}{2}\rho gh=1\,atm+\rho gh\] \[2\,atm=\rho gh-\frac{3}{2}\rho gh\] \[2\,atm=-\frac{\rho gh}{2}\] \[2\times {{10}^{5}}=-\frac{{{10}^{3}}\times 10\times h}{2}\] \[h=-40m\]
