    A spring of force constant k is cut into three equal parts. The force constant of each part would be

    A)  3 k                              

    B)  2 k

    C)  k                                 

    D)  \[\frac{k}{3}\]

    Correct Answer: A

    Solution :

    As, \[k\propto \frac{1}{l}\] \[\because \] Spring is divided into three parts, so length of each part becomes one-third of the original length. \[\therefore \] The spring constant of each part would be three times the spring constant of the complete spring.
