    Block A is on top of block B and block B is being pulled with a tension T. There is no friction between A and B nor is there friction between B and the floor. What is the ensuing motion of the blocks when T is applied? |dw:1331273978869:dw|

    \[T=(m _{A}+m _{B})a\]

    Okay. When we pull B for a while, what happens to A?

    hence no friction between them a go back

    no i mean block A go back notice that we assume no friction between 2masses

    Because there's no friction between blocks A and B, Block A goes back and falls down as we pull block B?

    welll if there is no friction between block A and B then the upper block fall down as due to ma lower block moves noe qn ariseswhen tension applied as by looking this case it seems like freely falling body because tension is applied but in which respect as no friction b/w block and floor if u applied a lil force or u dont it ll move due to its weight
