Two blocks are connected by a string as shown in the diagram. The upper block is hung by another string. A force F applied on the upper string produces an acceleration of \[2m/{{s}^{2}}\] in the upward direction in both the blocks. If T and \[{T}'\]  be the tensions in the two parts of the string, then [AMU (Engg.) 2000]

A. \[T=70.8N\] and \[{T}'=47.2N\]
B. \[T=58.8N\] and \[{T}'=47.2N\]
C. If assertion is true but reason is false.
D. \[T=70.8N\] and \[{T}'=0\]
Answer» B. \[T=58.8N\] and \[{T}'=47.2N\]
