Two 100N weights are attached to a spring scale as shown does the scale read 0N 100Nor 200N or does it give some other reading hint would it read any differently if one of the ropes were tied to the?

Answer 1

If two 100N weights are attached to a spring scale, the scale will read a total force of 200N because the weights are acting downwards, pulling the scale downwards. The scale would give the same reading even if one of the weights were tied to the rope as it would still be exerting a downward force on the scale.

Please note that the scale measures the total force acting on it, regardless of how the forces are distributed or connected.
