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 the 2 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 –
A
F
B
C
D
3F
Text Solution
Verified by ExpertsThe correct answer is:
D
Acceleration of two mass system is a = 
leftward
FBD of block A
N cos 60 0 – F = ma = 
solving N = 3F
