JEE Main & Advanced Physics Elasticity Question Bank Youngs Modulus and Breaking Stress

  • question_answer
    The increase in length is l of a wire of length L by the longitudinal stress. Then the stress is proportional to            [MP PET 1986]

    A) L/l           

    B)                 l/L

    C)                 \[l\times L\]            

    D)                 \[{{l}^{2}}\times L\]

    Correct Answer: B

    Solution :

        \[Stress\propto Strain\Rightarrow Stress\propto \frac{l}{L}\]
