    if u caluclte net force then it will be F as block M1 will aplly F force to M2 block and in turn M2 block will apply same amount force to block M1 so net force will be F

    Draw the force diagrams of each body. You will see that for the second body, N=M2a(If N is force applied by the blocks on each other and a is acceleration of the system). For first body F-N=M1a Now solve for N.

    a=F/(M1+M2) We apply a force F on the first body. But the body does not apply the same force on the other body. There is a sort of loss while the body transfers our force to the other body

    Why F-N=M1a?
