    In steel, the Youngs modulus and the strain at the breaking point are \[2\times {{10}^{11}}N/{{m}^{2}}\] and 0.15 respectively. The stress at the breaking point for steel is therefore

    A) \[9\times {{10}^{-6}}C\]               

    B) \[8.85\times {{10}^{-13}}C\]

    C)                        \[1.8\times {{10}^{-14}}C\]

    D)        \[\mu F\]

    Correct Answer: D

    Solution :

    Breaking stress = strain \[\times \] Youngs modulus \[=0.15\times 2\times {{10}^{11}}\] \[=3\times {{10}^{10}}N/{{m}^{2}}\]
