  • A block of mass 'm' is connected to another block of mass 'M' by a spring (massless) of spring constant 'k' The blocks are kept on a smooth horizontal plane. Initially the blocks are at rest and the spring is unstretched Then a constant force 'F' starts acting on the block of mass 'M' to pull it. Find the force on the block of mass 'm' :

    A
    `(MF)/((m+M))`
    B
    `(mF)/(M)`
    C
    `((M+m)F)/m`
    D
    `(mF)/((m+M))`

  • Four blocks each of mass M connected by a massless strings are pulled by a force F on a smooth horizontal surface, as shown in figure.

    A
    `T_(3) = 1/4 F`
    B

    C
    `T_(1) = 3/4 F`
    D
    `T_(1) = T_(2) = T_(3) = 1/2 F`
