    Which of the following graph depicts spring constant k versus length l of the spring correctly

    A)                

    B)

    C)                                              

    D)

    Correct Answer: D

    Solution :

                                    \[K=\frac{F}{x}\] and increment in length is proportional the original length i.e. \[x\propto l\] \[\therefore \]  \[K\propto \frac{1}{l}\]                 It means graph between K and l should be hyperbolic in nature.
