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] |
