Q148 / 180 · AIIMS 2007 · Physics

Shear modulus is zero for

A
solids
B
liquids
Correct answer
C
gases
D
liquids and gases

Solution

Even viscosity is due to shearing when flow takes place in stream lined motion. In gases, there is no shearing and therefore no shear modulus.

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