    Youngs modulus of the material of a wire is V. Oh pulling the wire by a force F, the increase in its length is \[x\]. The potential energy of the stretched wire is :

    A)  \[\frac{1}{2}Fx\]         

    B)  \[\frac{1}{2}Yx\]

    C)  \[\frac{1}{2}F{{x}^{2}}\]

    D)  none of these

    Correct Answer: A

    Solution :

    The potential energy of the stretched wire is                 \[U=\frac{1}{2}\times \] stress x strain \[=0.1%+0.1%=0.2%\]
