A) 100 N
B) 40 N
C) 50 N
D) Zero
Correct Answer: D
Solution :
Total mass of blocks A and \[B=2+8=10\text{ }kg\]Friction between surface and combination of A and B \[F=\mu R\] \[=0.5\times 10\times 10=50\,N\] Here applied force on box B is ION that is less than 50 N. So the system will be in rest because of this there is no friction between blocks A and B.You need to login to perform this action.
