Question

For an ideal liquid ______.

1. the bulk modulus is infinite.
2. the bulk modulus is zero. 
3. the shear modulus is infinite.
4. the shear modulus is zero.

Answer 1

a and d

Explanation:

Because as an ideal liquid is not compressible

Bulk modulus 

`(K) = (-p(V))/(ΔV)`  .......(∵ ΔV = 0)

As ΔV = 0 for ideal liquid

Therefore, K = ∞ for the ideal liquid

Since, no tangential force on the liquid, shearing strain

Δθ = 0, F = 0

`H = (F/A)/(Δθ) = 0/0` = indeterminate value
