A) \[\frac{g.g}{2}\]
B) \[\frac{g}{2},g\]
C) \[g.g\]
D) \[\frac{g}{2},\frac{g}{2}\]
Correct Answer: B
Solution :
When the string is cut, free body diagrams of blocks A and B are shown in the figure \[\therefore \]\[2m{{a}_{A}}=3mg-2mg\] \[{{a}_{A}}=\frac{mg}{2m}=\frac{g}{2}\] Free body diagram of block B shows \[m{{a}_{B}}=mg\] \[\therefore \] \[{{a}_{B}}=g\] Hence, the correction option is [b].You need to login to perform this action.
