    Forces forming a couple are of magnitude 12N each and the arm of the couple is 8m. The tone of an equivalent couple whose arm is 6 m is of magnitude:                            

    A)  8 N                                       

    B)                   16 N                                     

    C)                   12 N                                     

    D)                   4 N

    Correct Answer: B

    Solution :

    Since, the two couples are equivalent. Therefore their moments are equal. Hence,                  \[12\times 8=F\times 6\] \[\Rightarrow \]               \[F=16\,N\]
