  • question_answer
    Two springs have spring constants \[{{K}_{A}}\] and \[{{K}_{B}}\] and \[{{K}_{A}}>{{K}_{B}}\]. The work required to stretch them by same extension will be                                                                [RPMT 1999]

    A)            More in spring A                 

    B)            More in spring B

    C)            Equal in both                        

    D)            Noting can be said

    Correct Answer: A

    Solution :

                       Work done in stretching (W) µ Stiffness of spring (i.e. k) Q \[{{k}_{A}}>{{k}_{B}}\] Þ  \[{{W}_{A}}>{{W}_{B}}\]
