Bulk modulus and Poisson ratio of the material, the following relationship holds good A. $${\text{E}} = 3{\text{K}}\left( {1 – \frac{2}{{\text{m}}}} \right)$$ B. $${\text{E}} = 2{\text{N}}\left( {1 + \frac{1}{{\text{m}}}} \right)$$ C. $$\frac{3}{2}{\text{K}}\left( {1 – \frac{2}{{\text{m}}}} \right) = {\text{N}}\left( {1 + \frac{1}{{\text{m}}}} \right)$$ D. All the above
