This one always got me (including this time lol). Tension is 100N. If we pretend that one side is a wall, it's pulling with the same force as the other side, which is 100N. Net force is 0, but the tension must be 100N. Hence, the entire system is static.

A simpler way to view it is to remove the scale and pretend it's a 100N object attached to a wall by a string. Tension is easy to visualize as 100N in that case.

100 N.

100N

100

100N right there. This whole thing is in the state of equilibrium.

with the balance balancing. It’s 100N

100 N

200 N Just because they balance doesn't mean the force generated by them hanging is any less. If you nailed one end of the scale to the table, the force on the scale would be 100. Having them pull against each other would double that. That's my guess. 😁

this is a serious dilemma. I think the scale has to read 200N because weights shouldn't cancel out right 🤔 hold on weight is pressure so force can cancel out but I'll go with 200

It seems to me that the scale will indicate 100, because only the hook side will measure the force, the other end is only for holding and would have no influence no matter how much weight it has. That's what I think🤭
