Imagine you have two spring scales, A and B, connected at
the end of the scale that doesn't move. The end of the spring scale
that moves (where you take readings from) is attached to a string
which goes over a pulley and connects to a 1kg mass for both spring
scale A and B.
Please do the following:
State what you think EACH spring scale will read in this
situation.
Construct a logical argument explaining why the spring
