Question
Physics Question on mechanical properties of solids
Stress is the internal force per unit area of a body. Rubber is more elastic than steel.
A
If both the assertion and reason are true and reason is a correct explanation of the assertion
B
If both assertion and reason are true but assertion is not a correct explanation of the assertion
C
If the assertion is true but the reason is false
D
