Three identical blocks, A, B, and C, are on a horizontal frictionless table. The blocks are connected by strings of negligible mass, with block B between the other two blocks. If block C is pulled horizontally by a force of magnitude F = 28 N, find the tension in the string between blocks B and C.

    m1=m2=m3 =m,
    Total mass = 3 m.
    Acceleration of each block
    a= F/3•m.

    T is the tension in the string between blocks B and C.
    T is the pulling force on both masses B and A with an acceleration of a.
    T = 2ma = 2•m• F/(3m) = 2/3•F = (2/3) •28 =18.7 N
