    The Youngs modulus of the material of the wire of length L and radius r is \[\text{Y N}/{{\text{m}}^{\text{2}}}.\]If the length is reduced to L/2 and radius r/2, the Youngs modulus will be

    A)  \[\text{Y}/\text{2}\]                     

    B)  \[\text{Y}\]

    C)  2\[\text{Y}\]                                    

    D)  4\[\text{Y}\]

    Correct Answer: B

    Solution :

                     Youngs modulus depends upon the nature of Material and is independent of the dimensions of the material.
