Answer:
Let x be the force recorded by dynamometer.
Both masses move in one direction.
The largest force is 50 N and the least is 30 N.
This means x lies between 50 and 30.
This can be represented as shown.
30 < x < 50
The resultant force on :
6 kg mass = 50 - x
4 kg mass = x - 30
They have equal acceleration as shown :
6
(50−x)
=
4
(x−30)
200−x=6x−180
x=38N
