Block B has a mass of 4.2 kg and block A has a mass of 2.6 kg. They are in contact and slide over a frictionless horizontal surface. A force of 11 N acts on B.(force applied on block b then block a , they are beside each other)
what is the force on B due to A if the blocks are interchanged?

  • Physics -

    If the force is horizontal on B, pushing A

    net force=totalmass*a

    a=11/(4.2+2.6)

    so the force pushing on A, and A pushing on B, is 2.6*a
