Answer:
Explanation:
In this interesting exercise we have that spring A is 3 cm longer, due to previous experiments if these experiments did not reach the non-linear elongation point, the cosecant Km of the spring must remain the same, therefore when we lengthen the two springs these the longitudinal are lengthened.
As a consequence of the above according to Hockey law, the prediction of lengthening is the same, therefore the outside is the same in two two systems
F = K Δx
