    A square wire frame of size L is dropped in a liquid. On taking out, a membrane is formed. If the surface tension of &the liquid is T, force acting on the frame will be

    A)  \[2T.L\]                       

    B)  \[4T.L\]

    C)  \[8T.L\]

    D)  \[10T.L\]

    Correct Answer: C

    Solution :

                             As there are two sides of the film created, the total boundary of the film would be\[8L\]. Hence, force of surface tension will be \[8L\times T\].
