Question
Which modulus is not applicable for describing the elastic behavior of liquids and gases under shear stress?
Explanation
The shear modulus is not applicable for liquids and gases because they do not sustain shear stress and instead flow; only solids have a defined shear modulus. As per NCERT, applying relevant law/formula with correct units and sign convention leads to Shear modulus. This satisfies dimensional consistency and physical conditions given, so option D is scientifically correct.
