A) \[\left( \frac{3}{2\mu } \right)mg\]
B) \[\left( \frac{5}{2\mu } \right)mg\]
C) \[\frac{3}{2}\mu mg\]
D) \[\frac{5}{2}\mu mg\]
Correct Answer: B
Solution :
[b] : Total mass of the system \[=2m+m+2m=5m\] \[\therefore \]Horizontal acceleration of the system,\[a=\frac{F}{5m}\]..(i) Let N be the normal reaction between blocks B and C. From the free body diagram of C, as shown in figure.You need to login to perform this action.
