Answer 2

Answer:

Hlo

Explanation:

Considering the 6 kg block as a system ,

we get, T=6g=60N.........................(1)

As it will not move because other side the string is connected to the table.

Now,

for 4kg block as a system,

T−T1=4g,

T−T1=40,

60−T1=40,..........................from (1)

T1=20N
