Two blocks are connected by a string as ...

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

A

zero

B

3,3 N

C

13,3 N

D

19,6 N

Text Solution

Verified by Experts

The correct Answer is:
C

`F=70=(2+5)a=7xx2`
`F84N=T'`

`F=70=(2+5)a=7xx2`
`T'=60N`
