A) \[19.6\times {{10}^{8}}\,N/{{m}^{2}}\]
B) \[19.6\times {{10}^{-10}}\,N/{{m}^{2}}\]
C) \[19.6\times {{10}^{10}}\,N/{{m}^{2}}\]
D) \[19.6\times {{10}^{-8}}\,N/{{m}^{2}}\]
Correct Answer: A
Solution :
\[B=\frac{\Delta p}{\Delta V/V}=\frac{h\rho g}{0.1/100}=\frac{200\times {{10}^{3}}\times 9.8}{1/1000}\] \[=19.6\times {{10}^{8}}N/{{m}^{2}}\]
