The Young's modulus for a perfectly rigid body is
Correct answer: B. infinite
- A. zero
- B. infinite
- C. 1
- D. none of these
Explanation
Young's modulus (Y) is a measure of the stiffness of a material. For a perfectly rigid body, which does not deform under any stress, the Young's modulus is considered to be infinite because it experiences no strain regardless of the applied stress

About Physics of Solids
Solids are compared through crystal structure, amorphous arrangement, elasticity, plastic deformation, stress, strain and Young’s modulus. Electrical behavior depends on available charge carriers and band structure, so conductors, insulators and semiconductors must be distinguished from mechanical properties such as strength, stiffness and brittleness.
