If Y , K and η are the values of Young's modulus, bulk modulus and modulus of rigidity of any material respectively. Choose the correct relation for these parameters.

Step-by-step solution

Y - Young's modulus, K - Bulk modulus, η - modulus of rigidity We know that, Y = 3 k 1 - 2 σ ⇒ σ = 1 2 1 - Y 3 k                       . . . 1 ⇒ Y = 2 η 1 + σ ⇒ σ = Y 2 η - 1         . . . 2 From the equation 1 and the equation 2 1 2 1 - Y 3 k = Y 2 η - 1 ⇒ 1 - Y 3 k = Y η - 2 ⇒ Y 3 k = 3 - Y n ⇒ Y 3 k = 3 η - Y η ⇒ η Y 3 k = 3 η -
