Three blocks A, B and C, of masses $\displaystyle 4$ kg, $\displaystyle 2$ kg and $\displaystyle 1$ kg respectively, are in contact on a frictionless surface, as shown. If a force of $\displaystyle 14$ N is applied on the $\displaystyle 4$ kg block, then the contact force between A and B is :

Official answer
(2)
$\displaystyle 6$ N
