## Homework Statement

Since the image is not clear ,the blocks on the left are 1 Kg(top) and 5kg(bottom) connected by a spring. On the right are 1Kg(top) and 2Kg(bottom) .The bottom right string is cut .

## Homework Equations

## The Attempt at a Solution

Suppose T1 is the tension in string AB , T2 in string CD, T3 in EF and GH , T4(=kx) in the spring .Just after AB is cut T4 (i.e spring force) does not change . Tension in strings CD become T2' and in string EF and GH becomes T3' .

Writing force balance equation for the two 1 Kg blocks and 2Kg block ,

For the left 1Kg block , 6g - T3' = 1a

For the right 1Kg block , T3' -T2' - 1g = 1a

For the right 2Kg block , T2' - 2g = 2a

Solving , I get T3' = 21g/4 , but this isn't an option .

Please help me with the problem .

Thanks
