Answer 1

Answer:

Ans is 200N

Explanation:

F b/w A and B is 120N

we know, F=ma

we will take the sum of mass of block B and C because the thread is pulling both the block.

m = 4+2

m = 6kg

F = 120 N

a = F/m

a = 120/6 = 20m/s²

Now we know a

so, now we will take total mass

m=10

now, F=m*a

F= 20*10=200N

Answer 2

Answer:

200N

Explanation:

T=(4+2)F+4*0/10

120=6F/10

1200/6=F

F=200N
