Two block 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^(t)` be the tension in the two part of the string, then

A

`T=70.8N` and `T'=47.2N`

B

`T=58.8N` and `T'=47.2N`

C

`T=70.8N` and `T'=58.8N`

D

`T=70.8N` and `T'=0`
