Three blocks on a frictionless horizontal surface are in contact with each other as shown in $($Figure $1).$ A force F$$

is applied to block A $($mass mA

$).$

Figure$1$ of $1$

Three blocks lie on a horizontal surface in a row. The blocks have masses m A$,$ m B$,$ and m C from left to right, respectively. All adjoining blocks are in contact. A horizontal force F is applied rightward to the leftmost block.
