Question

In the given figure, the force is applied on block B. The co-efficient of friction for different contact surface is as shown in figure. Choose the correct option (s)

• A. if $F=6N$, there is no motion at any part of the system
• B. if $F>12N$, there is motion between A and B
• C. If $F>11N$, there is motion between B and C
• D. if $F<6N$, there is motion between A and B
