A spherical ball of volume \(2000 \mathrm{~cm}^3\) is subjected to a hydraulic pressure of \(15 \mathrm{~atm}\). If the change in volume is \(5 \times 10^{-2} \mathrm{~cm}^3\), the bulk modules of the material of the spherical ball is
\(\left(1 \mathrm{~atm}=10^5 \mathrm{Nm}^{-2}\right)\)
- A \(6 \times 10^{10} \mathrm{Nm}^{-2}\)
- B \(2 \times 10^{10} \mathrm{Nm}^{-2}\)
- C \(5 \times 10^{10} \mathrm{Nm}^{-2}\)
- D \(15 \times 10^{10} \mathrm{Nm}^{-2}\)
