An object is located at 2 km beneath the surface of the water. If the fractional compression

\frac{{\Delta V}}{V}

is 1.36%, the ratio of hydraulic stress to the corresponding hydraulic strain will be………
(Take, density of water is

1000\,\mathrm{ }kg\mathrm{ }\,{m^{ - 3}}

and

g = 9.81\,\mathrm{ m}\,{\mathrm{s}^{ - 2}}

)

View answer and explanation

Correct option: D

1.44 \times {10^9}\mathrm{N}{m^{ - 2}}

Option D (

\tan ^{-1}\left(\frac{4}{3}\right)

) is correct because the phase angle is calculated using the inductive reactance and resistance.
