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.
1
\(k=\frac{Y \eta}{9 \eta-3 Y} N / m^2\)
2
\(\eta=\frac{3 Y K}{9 K+Y} N / m^2\)
3
\(Y=\frac{9 K \eta}{3 K-\eta} N / m^2\)
4
\(Y=\frac{9 K \eta}{2 \eta+3 K} N / m^2\)
