Answer
- The bulk modulus is infinite.
- The shear modulus is zero.
Explanation:
An ideal liquid is not compressible.
Bulk modulus $(\text{K})=\frac{-\text{p(V)}}{\Delta\text{V}} (\because\Delta\text{V=0})$
$\because\Delta\text{V=0}$ for ideal liquid.
$\therefore\text{K=}\infty$ for ideal liquid.
As there is no net tangential force on liquid (S.T. is all around on a particle) so shearing strain $\Delta\theta=0\text{ and F=0.}$
$\eta=\frac{\text{F/A}}{\Delta\theta}=\frac{0}{0}$ indeterminant value.
Hence, verifies option (a) and (d) and rejects option (b, c).
