Q. On a smooth horizontal surface two blocks of mass 2 kg and 8 kg are placed as shown. Two horizontal forces of 10 N and 50 N are being applied as shown. What is the normal reaction between the blocks ?

Two blocks 'A' and 'B' each of mass 'm' are placed on a smooth horizontal surface. Two horizontal force F and 2F are applied on both the blocks 'A' and 'B' respectively as shown in figure. The block A does not slide on block B. Then the normal reaction acting between the two blocks is: (Assume no friction between blocks)
