Q. Assertion: Steel is more elastic than rubber.
Reason: Under a given deforming force steel is deformed less than rubber.

Answer 1

Correct Answer - A
The internal restoring force acting per unit area of cross-section of the deformed body is called stress. Also elasticity is the property of the material of a body by virtue of which it opposes any change in its size or shape. Greater the force required more elastic the body is. Hence, steel is more elastic than rubber.
