If the Young's modulus of the material is 3 times its modulus of rigidity, then its volume elasticity will be

(a) Zero                                          (b) Infinity

(c) 2×1010N/m2                           (d) 3×1010N/m2

(b) Y=2η1+σ3η=2η1+σσ=32-1=12

Now substituting the value of s in the following expression.

Y=3K1-2σK=Y31-2σ=
