Bulk modulus of water is \(2 \times 10^9 \mathrm{~N} / \mathrm{m}^2\). The pressure required to increase the volume of water by \(0.1 \%\) in \(\mathrm{N} / \mathrm{m}^2\) is :
- A \(2 \times 10^9\)
- B \(2 \times 10^0\)
- C \(2 \times 10^6\)
- D \(2 \times 10^4\)
Answer & Solution
Correct Answer
(C) \(2 \times 10^6\)
Step-by-step Solution
Detailed explanation
Bulk modulus, \(K=2 \times 10^9 \mathrm{~N} / \mathrm{m}^2\) Change in volume, \(\Delta V=0.1 \%\) of initial volume \(=0.1 \%\) of \(V=\frac{V \times 0.1}{100}=V \times 10^{-3}\) \(\therefore \quad K=\frac{p V}{\Delta V}\) \(2 \times 10^9=\frac{p \times V}{V \times 10^{-3}}\)…
