    The Youngs modulus of a wire of length L and radius r is \[Y\,N/{{m}^{2}}\]. The length and radius are reduced to \[\frac{L}{6}\] and \[\frac{r}{6}\], then its Youngs modulus is

    A)  6 Y               

    B)  \[\frac{Y}{6}\]

    C)  Y                     

    D)  3Y

    Correct Answer: C

    Solution :

    Youngs modulus of a wire does not vary with dimensions of wire. It is the property of given material.
