A) \[7.5\times {{10}^{10}}N{{m}^{-2}}\]
B) \[7.5\times {{10}^{8}}\text{ }N{{m}^{-2}}\]
C) \[7.5\times {{10}^{6}}N{{m}^{-2}}\]
D) \[7.5\times {{10}^{4}}N{{m}^{-2}}\]
E) \[7.5\times {{10}^{2}}N{{m}^{-2}}\]
Correct Answer: B
Solution :
Given, \[\frac{\Delta V}{V}\times 100=1%=\frac{1}{100}\] Bulk modulus, \[B=\frac{p}{\Delta V/V}=\frac{pV}{\Delta V}\] Or \[p=\frac{B\Delta V}{V}=7.5\times {{10}^{10}}\times \frac{1}{100}\] \[=7.5\times {{10}^{8}}N{{m}^{-2}}\]
