1.	Mark the wrong statementA. Sliding of molecular layer is much easier than compression or expansion.B. Reciprocal of bulk modulus of elasticity is called compressibilityC. It is difficult to twist a long rod as compared to small rodD. Hollow shaft is much stronger than a solid rod of same length and same mass
Answer» Correct Answer - C For twisting, angle of shear `phiprop(1)/(L)` i.e., if `L` is more than `phi` will be small.
