A) \[19.6\times {{10}^{8}}\text{N/}{{\text{m}}^{\text{2}}}\]
B) \[19.2\times {{10}^{7}}\text{N/}{{\text{m}}^{\text{2}}}\]
C) \[2.4\times {{10}^{9}}\text{N/}{{\text{m}}^{\text{2}}}\]
D) \[2.4\times {{10}^{5}}\text{N/}{{\text{m}}^{\text{2}}}\]
Correct Answer: A
Solution :
\[K=\frac{\text{p}}{\text{Volume}\,\text{strain}}=\frac{hdg}{\text{Volume}\,\text{strain}}\] \[=\frac{200\times {{10}^{3}}\times 9.8}{0.1\times {{10}^{-2}}}\] \[=19.6\times {{10}^{8}}N\text{/}{{m}^{2}}\]
