JEE Main & Advanced Physics Elasticity Question Bank Bulk Modulus

  • question_answer
    A uniform cube is subjected to volume compression. If each side is decreased by 1%, then bulk strain is [EAMCET (Engg.) 1995; DPMT 2000]                

    A)                                 0.01                       

    B)                                 0.06                

    C)                                 0.02                       

    D)                                 0.03                

    Correct Answer: D

    Solution :

                        If side of the cube is L then \[V={{L}^{3}}\] Þ \[\frac{dV}{V}=3\frac{dL}{L}\] \ % change in volume = 3 × (% change in length)             = 3 × 1% = 3% \ Bulk strain \[\frac{\Delta V}{V}=0.03\]
