    A rope of length 5m is kept on frictionless surface and a force of 5N is applied to one of its end. Find tension in the rope at 1m from this end                                 [RPET 2000]

    A)             1 N     

    B)             3 N

    C)             4 N

    D)               5 N

    Correct Answer: C

    Solution :

                    \[T=\frac{F(L-x)}{L}=\frac{5(5-1)}{5}=4N\]
