A block A of mass $\displaystyle 4$ kg is placed on another block B of mass $\displaystyle 5$ kg, and the block B rests on a smooth horizontal table. If the minimum force that can be applied on A so that both the blocks move together is $\displaystyle 12$ N, the maximum force that can be applied on B for the blocks to move together will be :
Official answer
(3)
$\displaystyle 27$ N
