A solid copper cube of \(7 \mathrm{~cm}\) edge is subjected to a hydraulic pressure of \(8000 \mathrm{kPa}\). The volume contraction of the copper cube is (Bulk modulus of copper \(=140 \mathrm{GPa}\) )
- A \(196 \times 10^{-3} \mathrm{~cm}^3\)
- B \(19.6 \times 10^6 \mathrm{~cm}^3\)
- C \(19.6 \times 10^{-3} \mathrm{~cm}^3\)
- D \(196 \times 10^3 \mathrm{~cm}^3\)
Answer & Solution
Correct Answer
(C) \(19.6 \times 10^{-3} \mathrm{~cm}^3\)
Step-by-step Solution
Detailed explanation
Given, edge of solid copper cube, \(l=7 \mathrm{~cm}\) hydraulic pressure, \(p=8000 \mathrm{kPa}=8000 \times 10^3 \mathrm{~Pa}\) and Bulk modulus of copper, \(\beta=140 \mathrm{GPa}\) \(=140 \times 10^9 \mathrm{~Pa}\) As we know that,…
