If the bulk modulus of water is \(2 \times 10^9 \mathrm{Nm}^{-2}\), then the required pressure to reduce the given volume of water by \(2 \%\) is
- A \(2 \times 10^7 \mathrm{Nm}^{-2}\)
- B \(4 \times 10^7 \mathrm{Nm}^{-2}\)
- C \(8 \times 10^6 \mathrm{Nm}^{-2}\)
- D \(5 \times 10^7 \mathrm{Nm}^{-2}\)
Answer & Solution
Correct Answer
(B) \(4 \times 10^7 \mathrm{Nm}^{-2}\)
Step-by-step Solution
Detailed explanation
Given that, \(B=2 \times 10^9 \mathrm{~N} / \mathrm{m}^2\) \(\frac{\Delta V}{V} \times 100 \%=-2 \% \Rightarrow \frac{\Delta V}{V}=\frac{-2}{100}=\frac{-1}{50}\) Now,…
