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 $2\,m/{s^2}$ in the upward direction in both the blocks. If $T$ and $T'$ be the tensions in the two parts of the string, then $T$ and $T'$

  • C

    $T = 70.8N$ and $T' = 58.8N$

  • D

    $T = 70.8N$ and $T' = 0$
