The relation between young's modulus $(Y)$, bulk modulus $(K)$ and modulus of elasticity $(q)$ is

• A

  $\frac{3}{Y}=\frac{1}{K}+\frac{3}{q}$
• Correct answer
  B

  $\frac{3}{Y}=\frac{1}{q}+\frac{1}{3 K}$
• C

  $\frac{1}{Y}=\frac{3}{q}+\frac{1}{3 K}$
• D

  $\frac{1}{q}=\frac{3}{Y}+\frac{1}{3 K}$

Hence, the correct answer is option: 'B'.
