A submarine experiences a pressure of $\displaystyle 5.05 \times 10^6 \mathrm{~Pa}$ at a depth of $\displaystyle \mathrm{d}_1$ in a sea. When it goes further to a depth of $\displaystyle \mathrm{d}_2$, it experiences a pressure of $\displaystyle 8.08 \times 10^6 \mathrm{~Pa}$. Then $\displaystyle \mathrm{d}_2-\mathrm{d}_1$ is approximately (density of water $\displaystyle =10^3 \mathrm{~kg} / \mathrm{m}^3$ and acceleration due to gravity $\displaystyle =10 \mathrm{~ms}^{-2}$ ):
