The approximate depth of an ocean is $2700 m$ . The compressibility of water is $45.4 \times 10^{- 11} P a^{- 1}$ and density of water is $10^{3}$ ${kg/m}^{3}$ . What fractional compression of water will be obtained at the bottom of the ocean ?NEET 2015 (Phase 1)

Options:

Answer:

Solution:

Pressure at the bottom of the ocean
$P = ρ g d$
$= 10^{3} \times 10 \times 2700$
$= 27 \times 10^{6} P a$
$∴$ Fractional compression = compressibility $\times$ pressure
$= 45.4 \times 10^{- 11} P a^{- 1} \times 27 \times 10^{6} P a$
$= 1.2 \times 10^{- 2}$
