Hello Friend, I will show a very simple method to do this problem ..but for that you should draw the Free Body Diagrams of each block and mark the forces acting on it , let T1 be the tensio of string among block 2-3 kg and T2 be the tension of stringbetween 3-5 kg blocks
On block 1 with mass 2 kg
F-T1=2xa=2 N
T1=8N ..here i subtracted the F and T1 because they are opposite to each other and keep in mind that they are moving to the right with 1m/s2 acceleration
on block with 3 kg
T1-T2=3xa=3N
which implies that T2 is 5N as T1 was 8N
There fore you have the answer ..for all this kind .. draw Free Body Diagrams and mark all forces acting on it and equate ..
Hope this helps
